Hi Team,
My board clock requirement block diagram is attached below.
The clock from the clock synthesizer need to feed as input clock to all ADC, DAC and FPGA in the board to make a synchronization.
Also from FPGA an input SYNC IN/ LDAC like input signal is fed to all the ADCs and DACs so that FPGA can control and sync activities of all the data converters.
My requirement is 16-bit 33MSPS SPI DACs (single or dual channel). We look upon on SPI DACs because of less pin input for SPI. But I didn't find any SPI data with CLK IN pin .
Then i searched LVDS and CMOS DACs, there i could get CLK IN as per my requirement. But these CMOS input signals for DAC8812 are 16+16, 32pin data inputs along with several control signals. But i required 4-5 DACs in the board, if i use 5 DACs total input pins from the SOM/FPGA must be minimum 32*5 160data input pins. I can't afford that much pins from my FPGA. So can you please suggest a DAC for my requirement that less no of input pins. LVDS DACs is also fine for my requirement, but i must a single P/N input signal for the DAC, but 16P/N inputs signals for a single DAC, i can't give.
Please provide a suggestion for my query.
Regards,
Abhishek
