The LTC2387-16 has a one or two lane DDR LVDS serial i/f which has to be clocked at 89MHz+ in two lane mode to achieve 15MSPS (data is sampled on both clock edges). What would be the easiest/cheapest way to interface it to an M3 or M4 Cortex MCU? I'm fairly flexible about the exact choice of MCU however.
The demo boards, DC2290A and DC2588A, use a Cyclone 3 EP3C5E144 which aren't exactly cheap. I've never done any FPGA development beyond some simple PALs several decades ago, so simplicity is desirable but cost is the most important issue. Ideally I prefer to avoid an FPGA/CPLD solution to avoid the learning time (though that could be interesting and useful for the future). Are there any low cost off the shelf shift registers with LVDS clock and serial data inputs and CMOS level outputs?
I wonder why LT and Analogue didn't make their parts easier to use? They could have provided a wider interface - a six bit CMOS interface would have used 1 less pin and could have interfaced directly to a (fast) MCU or via some jelly bean logic. I guess they assumed that an FPGA would be required anyway by most customers to process 15 MSPS of data. I see that TI at least are now using a 'Multi-SPI' interface on some newer convertors which can be up to 4 bits wide (although they aren't anywhere near 15MSPS).
