Hi -

I saw some previous threads on high-speed ADC design applications and I was wondering if someone could help me in picking out the right FPGA-based data capture+pattern generator board and ADC, DAC modules for our system. The ADC should support 200 MHz BW for an optical pulse signal that is 50-100 ns wide, with repetition rate of 1-2 MHz and 0.4-4.26 Vpp. Also, the DAC modules should be able to drive one TTL pulse and two 10Vpp sine waves of ~1 KHz. The data capture/pattern generator should be able to interface with both the DAC and ADC modules. Also, it should have an on-board crystal oscillator and shouldn't require an external clock. Also, the data capture board should be able to serially transfer the acquired data ~2 MBps or higher to the PC. We are basically looking at medical imaging or OCT applications if that makes more sense. With these design requirements, I came across a couple of options and I would really appreciate any feedback/input that you could provide:

ADS4229 Dual-Channel, 12-Bit, 250-MSPS + TSW1400EVM (requires external RF clock)

ADS5517 11-Bit, 200-MSPS + TSW1400EVM

TIDA-00826/ TIDA-010128 (Too bulky and difficult to program)

Any ADC + TSW14J57EVM

Thank you very much once again!

Best,

Yamuna

Hi Jim,

Thanks for the suggestions. Will I be able to program the FPGA on TSW data capture or pattern generator board or do I need an external development or evaluation kit along with the TSW in case I want to interface both ADC-DAC modules?

Best,

Yamuna

Yamuna,

You can program the FPGA on all of our TSW platforms. The TSW1400 does require you to move some resistors though. The others do not. You will need either the Xilinx or Intel (Altera) software, depending on which board you order.

Regards,

Jim

Thank you, Jim. I think the TSW14J57 meets our requirements best, interfaced with ADS54J42EVM. But I am still not sure if I will be able to trigger the TSW with both ADC and DAC modules at the same time. Could you suggest a DAC module that could be interfaced and has a trigger out ~1-2 MHz fast? Is it also possible to do any on- board signal processing with the acquired data (images)?

This board only has one connector. You cannot plug in both an ADC and DAC board at the same time.
