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 DAC required output range is +/-1.85V.

Can i use the DAC3484 for my application.

If yes please suggest an output buffer amplifier to DAC IC so that i need a single ended output to be connected to a SMA connector.

Please provide an update on above mentioned query.

Regards,

Abhishek

HI team,

Is there any IC which has CMOS clock input for FPGA synchronization or clock synthesizer clock synchronization.

Hi Abhishek,

Combining this with your other thread here: DAC3283: DAC3283: Design Inquiry

It sounds like you may just need a simple LVCMOS clock buffer, would something like LMK1C1108 work for your application? Or do you need a clock generator with support for JESD204 for synchronization across all of your ADCs and DACs?

Connor

Hi Connor,

I had enquired about the DAC IC not the clock buffer. Please provide an update on DAC requirement.
