Acute Logic & Lead CCTV PE-1005S HD Camera Module
« on: September 28, 2019, 08:50:51 am »
Over in the for sale section several forum members have picked up some of these high-def camera modules. I thought i'd start this thread so we can pool some resources together and see if we can get something meaningful out of the cameras.

https://www.eevblog.com/forum/buysellwanted/cameras-uk-burnley)/

The module is a HD video camera with upto 1080p30 output as '16bit YUV 4:2:2' which could mean several things TBH, i am going to hazard a guess it's something like bt.601 but  :-//

The maker is indicated as ACUTE Logic. A Japanese company they seem to have sold their camera module business to a Chinese company in 2011 so i guess these cameras predate that.

I am sure I have more docs but for the moment can only find this:

Edit: Found some more. There is an XLS file here where I started working out the connections but didn't get too far. :) I am sure you know all about that.

i heard back from Acute Logic with a nice polite reply to goto the Chinese company the tech was sold to... so nothing there. We'll see what we can get from LeadCCTV in China.

I've seen this device under the Hitachi banner too which may be a useful source of information if anyone has old data, if we know the vintage it may be possible to track down contemporary products but I *think* this unit was intended for videoconferencing equipment

Has anyone had any luck getting in touch with these companies?

I sent LeadCCTV an email regarding their HDMI adapter boards a few days ago and still no reply. Chrome won't let me translate their website either so I'm not sure where to go from here.

It's one of the very few things on their website so if they're still going I'd imagine they'd be quite keen to sell them!

Close but no cigar (yet)

There's a Leonid Tochinsky with some experience here:

Maybe someone with a TI account can see if he's still active and ask?

Hardware specification attached, lots more tech detail in this one including connector & pinout specification. though nothing for the i2c protocol which is in a separate document that i have already asked for.

Important details:
Connector is a Panasonic AXT360264
Power is two rails 4v @ 450ma and 2.8v @ 270ma
There is a PON signal, pulled high by the host for power on
Default video mode is 1920x1080 @ 30 fps

Video is indeed YUV 4:2:2, there's 16 data lines, clock, H sync and V sync. The Y and C is a combined word, so you get a luma and a chroma sample on every rising clock.

lower 8 bits are the luma content
upper 8 bits are chroma Cb or Cr

Clock is 66mhz, this seems to be fixed regardless of the video mode

The most ideal output for me would be 1080p25 as HD-SDI

some slight confusion about the connector... the camera datasheet says it's AXT360264 but that doesn't exist according to Panasonic, i think it should be AXT360224 for the socket and AXT460124 for the header

It doesn't seem like there's much going on from this thread but that's not the case.

ElectronAsh (https://twitter.com/AshEvans81) is on board and has a couple of the cameras, over the last day or so we have looked at it in detail, he's designing a PCB that the camera will mount directly onto and will include an fpga that he can use as some kind of development mule. It's not really a recommended solution, to have the camera board-to-board but we figured lets just get this up and making a picture before we start getting fancy with flat-flex cables and stuff.

Currently it's looking like camera -> fpga/ram -> hdmi

The picture is probably going to be buffered in ram first, issues with the clock timing mean this is probably inevitable

We did look into HD-SDI as an output but we couldn't find any suitable SDI serialisers that were cheap enough and not BGA. HDMI can be converted to SDI anyway pretty cheap. In the future we could potentially include a SMPTE compliant parallel output for connection to a serialiser.

Will keep you all posted.

quick update,

ElectronAsh has been working on a PCB for this just to get something up and running, it's essentially FPGA and HDMI as that is what Ash works with all the time. The camera is mounted directly on the PCB to save the expense of a flat flex.

He's just about to order a few of these boards and will be doing all the work on the FPGA, funding the PCBs and component purchase himself, so we can't thank him enough! Those of us interested in getting these cameras working should consider helping him out with some extra funds as things progress.

Hi,

Firstly, a big thanks to Mjolinor for offering the cameras, and sending me a few. Very generous of you.


It's going to be tricky for me atm to get a batch of boards assembled by a company, mainly due to finances and time, as I'm working on many different projects atm.

I'm hoping to build two or three boards first, then confirm they work OK. I don't like to release anything until it's tested obviously.

I've tried to double-check what I can on the design, like the measurements for the header to the cam module, distances for the mounting holes, supply rails for the FPGA IO banks, which pins on the cam module needed pull-ups or tied to GND/VCC etc.

This is my first project using the MAX10, though, so that may require a few tweaks if I've missed something.

My usual go-to FPGA has been the Cyclone III for the past 4-5 years, as it can still be bought in the TQFP144 package for manual soldering. I've yet to get my reflow oven up-and-running so I can start using BGA stuff.

The MAX10 does have a fair few advantages. It frees up more IO pins (and every one is precious. lol), does away with one or two extra voltage regs, since it can run on a single 3V3 supply, and obviously it doesn't require external SPI Flash for configuration, so there's a slight saving there.

I'll be sending off for say 5 PCBs via PCBway in the next day or two, but I've been trying to get a couple of other designs done in the mean time, so I can get them shipped all at once.

If I don't manage to finish the other designs by about the weekend, I'll just order the 5 camera board PCBs, then build a few myself.


I've used the ADV7513 HDMI chip in many previous projects, and it's used on dev boards like the Terasic C5G and DE10 Nano / MiSTer.

The main challenge with the camera modules is that they apparently have a fixed pixel clock output of 66 MHz. Rather than having to buffer a full frame (requiring a larger FPGA and external RAM), I'm hoping to just use line buffers on the FPGA to get some image output via HDMI.

What I didn't quite get at first, is how the camera manages to output 1080p with pixel clock of only 66 MHz.

It should in theory be outputting one Luma sample per clock, and of course a Cb or Cr sample on every alternate clock.
But that still didn't seem to be a high enough pixel clock for 1080p?

And then Mr Dexter reminded me that it's 1080p at a max of 30 FPS. lol

So yep, the usual pixel clock for 1080p 60Hz via HDMI is 148.5 MHz, and 30Hz (or 1080i@60hz) would only be around 74.25 MHz.

Plus, I don't think the datasheet for the cam includes the blanking intervals in that spec, so 66 MHz should be plenty of bandwidth for the active pixels / lines.

In summary - a full framebuffer hopefully won't be required for generating the HDMI output, and making the most of the cam module, but we'll see.


P.S. ElectronAsh == OzOne.

btw, the PCB will be 2-layer for now.

tbh, 4-layer PCBs don't cost a huge amount more these days, but I don't think it's really necessary for this board. Although, it would probably have made the routing a fair bit easier. lol

(I prefer to use Eagle for the small-ish projects, as I'm still learning to use things like the library editor on Altium. I've been using Eagle for about ten years now, and just find it a lot quicker to get projects started on. For anything more complex, like multi-layer boards, I can import Eagle projects into Altium quite easily. Altium is a lot nicer for routing multi-layer stuff.)

I have done some estimates on the power dissipation of the voltage regs on the cam board, but will be adding some copper pours to act as heatsinks on some of them.

I'm running all three voltage regs (3V3, then 2V8 + 4V0 for the cam) from the 5V input atm.

As Mr Dexter said in a previous post, the cam is said to draw around 450ma (for the motors) on the 4V rail, and 270ma on the 2V8 rail.

I don't expect the FPGA and HDMI chip to draw much more than around 150mA from the 3V3 reg.

Realising that there wouldn't be much of a voltage drop from 5V to 4V (for the cam motor supply), I changed from using the LM1117 to the TLV75801, which has a low-dropout of only around 130mA...

https://www.ti.com/store/ti/en/p/product/?p=TLV75801PDBVR

All three regs will be in a SOT-223 package.


If anyone could help calculate the rough power dissipation for those (all with a 5V input), that would help a lot, since I struggle a bit with that stuff.

I can add copper pours on both the top and bottom layers for the three regs, with some connecting vias around the "tabs".

I think it'll be OK with a bit of copper added for heatsinking. Failing that, it is essentially just a test board atm, so we could stick on some small heatsinks if need be.

There is one bit of "feature creep" added...

The MIPI standard is becoming more and more popular on most mobile phone screens now, but it's also of course used on the CSI socket on the Rasp Pi.

I don't know if it will work out yet, but I added the footprint for a 15-pin 0.5mm FPC to the "underside" of the board, so it can be connected directly to the MIPI CSI cam port on the Pi.

My main reference material for this was Mike's superb video series on MIPI..




So yeah, it was just something fairly quick to add to the board. If it doesn't work, then it was worth a try.

But if it does work, it could turn the cam module into a nice little camcorder or wifi cam, with a Pi Zero W hooked up.


There's also a PCM1808 ADC chip on the board, so we can get some audio routed through to the HDMI port.
If I get chance, I might add a 3.5mm socket for line-level audio.

Should be simple enough to tweak the design later by adding electret or MEMs mics.

I ordered ten of the PCBs via PCBway last night, plus a stencil for solder paste.

(mainly for the tiny Panasonic connector for the cam.)

This will be my first time using solder paste at home, so it could get interesting. lol

I'll probably just manually solder the other parts. Once the FPGA and HDMI chips are soldered, the rest is straighforward.


When I first uploaded the Gerbers, I chose 5/5 width/spacing, as I thought I had quite a few areas where the spacing was below 6 mil.

But there were only about five traces on the other design (Atari ST VGA/HDMI board) which needed to be tweaked.

The cam board was already fine with 6/6 mil, so it worked out quite a bit cheaper.

For ten PCBs (for each design), it was only $6.
With the original 5/5 spacing, it was $32, so quite a big difference in cost.

(the minimum trace width on the whole board is 6 mil, but the clearance between the traces and ground pours was only 5 mil in some places. I just had to change the DRC settings, then hit the Ratsnest button again to fix it.)


In my haste to get the boards ordered, I did forget to add some vias and copper pours for the regulators.
Hopefully it won't be too bad on the dissipation, or may require small heatsinks on one or two of them.

Not much of a voltage drop from the 5V input anyway.

If it will help I have a reflow oven not doing owt that I can lend out but it will have to be picked up and brought back. I am not posting it so it needs to be someone close-ish to Burnley.

It is one of these:

Thanks. Much appreciated.

I'll see if I can give it a go with some solder paste first, as I've ordered a stencil for the board.

I can solder the rest of the components manually, but I have a feeling the tiny connector might be tricky.

The pitch is so fine, I imagine the stencil will just run lines of solder paste across the pads anyway, so I'll try with the hot air station.

The PCBs have just been shipped, and the parts arrived from Mouser yesterday.

I'll keep this thread updated on progress.

PCBs and stencil arrived...

I'm surprised that they were still able to cut the tiny holes in the stencil for the camera connector.

Now I need to buy some solder paste. Might as well try doing the whole board using the stencil, too.

Still no reflow oven working, so I'll probably just use the stencil for the connector using the hot air station, then manually solder the rest.
