DAC3151: DACCLK

Part Number:DAC3151

Hi

For DAC3151, please help with below questions. Thanks!

1.What is the relationship of DATA CLK and DAC CLK? If data rate is 400MHz, then DATA CLK and DAC CLK are both 400MHz?

2.Is DATA CLK and DAC CLK must from same clk source?

3.Customer tend to provide DAC CLK from FPGA. Is it ok?

4.FPGA CLK output is LVDS, but DAC CLK needs LVPECL. Is it ok?

Regards

David
