MCU read ADC LVDS output

[arul]

Hi All,

I need some advise regarding ADC interface with Microcontroller.

Here, that ADC(Analog to Digital Converter) output is serial LVDS(Low Voltage Differential Signal). How to read the ADC value using microcontroller(MCU)?

I have been come across with that attached block diagram.


In this block diagram, I read analog value using ADC. That ADC output configuration is LVDS(Low Voltage Differential Signal), so that LVDS is converted into TTL level. After that ADC value is passed to Microcontroller. The level shifter is added in between MCU and LVDS-TTL converter, if needed only because of MCU operating logic level.

Is it correct? Please give more suggestion and recommend which MCU, ADC are suitable for that.

Thanks all

there isn't enough information here.

First you should try to use an ADC that communicates via SPI or else i2c.  in that case you can directly connect it to the mcu.

if you use an ADC with the LVDS output then you should try to find a transceiver that works at the logic level of your micro - example 3.3V.

I think you have your design route backwards. You first select your ADC and MCU (or FPGA, since pretty much all of the ADCs that use LVDS as an output interface are very fast), then worry about all of the rest. Why fixate on using LVDS when the rest of your system is not chosen?
