DAC5672: BPSK Generation Application

Sipahee Lal
Prodigy 10 points
Part Number: DAC5672


Tool/software:

Hello Team, 

we want to generate a 600Hz sine wave output by using :channel-A of DAC5672 & channel B is unused. the code is generated by FPGA. The FPGA provides generates digital codes to DAC5672 as below.

1. DAC_CLK: 625KHz( delayed clock more than 4 ns)

2. DAC_WRTA: same as DAC clock

3. DAC_Code(DA13-0): generated by FPGA logic.

4. Mode : High

we observed that all the inputs on the dac are coming but we won't be able to see any activity at the channelA output port.

kindly suggest any solution.

Thanks & Regards

    Hi Sipahee,

    Can you please send over your schematics? I would like to see how the DAC is being setup?

    Have you verified your input timing of the data bits and the data clock per Figure 17 or 18 in the datasheet?

    Regards,

    Rob
