Part Number: DAC37J82

Dear team,

My customer needs TI support for configuring the DAC37J82 ASAP.

Below you can see the block diagram of the DAC37J82 in their system.

they will use all the 8 lanes, and per BW needs to operate at ~2Gbps/lane.

DACCLK and SYSREF are configurable as you can from the block diagram (By PLL)

 

Could you please provide us the parameters for configuring the DAC37J82 and frequencies of DACCLK and SYSREF.

Thanks in advance and regards,

Shai

    2. Interpolation factor.

    3. LMFS setting you plan on using.

    4. K value.

    5. SYSREF frequency.

    6. Do you plan on using the NCO? If so, what frequency.
