Other Parts Discussed in Thread: ADC12DJ3200, ADC12DL3200

I would like to consider high-speed ADC and DAC in radar technology research.

ADC sampling clock It is searching for devices that can input 4 GHz and has low latency.
The same is true for DAC.

Hi Hosoki,

The ADC12DJ3200 can accept up to 6.4 GHz sampling clock, and the DAC38RF8x is capable of 9 GHz sample clock. Both of these use the JESD interface for digital data. What is the latency requirement?

Best Regards,

Dan

thank you for your answer.

I want to make interface LVDS because I want to achieve high latency.
However, LVDS recognizes that about 1 Gbps is the limit.

What is the best configuration for 4 GHz?
Is ADC parallel 2 GHz? In that case clock devices, wiring etc.

Hi Hosoki
The ADC12DL3200 is a new LVDS interface ADC that can support 1 input at up to 6.4 GSPS or 2 inputs at up to 3.2 GSPS.
There are four 12-bit LVDS data buses. Each bus operates at up to 1600 Mbps. Each data bus has an associated output DCLK signal and strobe signal to ease capture alignment in the FPGA.
Best regards,
Jim B
