One of my customer is looking for low latency high-speed ADC and DAC.
His application is to capture high frequency signal by high-speed ADC and the data is processed by FPGA and output control signal from the FPGA and is converted to high-speed DAC. This is a feedback control system for high frequency radar system testing.
Because of the feedback control system, the delay time from input of ADC to Analog output from high-speed DAC is very important.
His requirement is >=1GSPS, >=12bits, simple ADC and DAC function, no filtering and frequency converter are needed.
I picked up the following high-speed ADC and DAC for this application.
AD9234: 12 bit 1 GSPS, Delay min=55 clocks
AD9680: 14 bit 1.25 GSPS, Delay min=55 clocks
AD9789, 14 bit 2.4 GSPS, Delay min=7 clocks
AD9735/6, 12/14 bit 1.2 GSPS, Delay min=32 clocks
If you have any other recommendation for this application, please advise me.
