Other Parts Discussed in Thread: LMK04816
Hello!
I have a custom DAC38RF89 board with no JTAG available.
Here is my use conditions:
- dacclk=328MHz, PLL, interpolation=24
- single DAC, LMFS=22210, K=16
- JESD204b subclass 0 (sysref internally genereted)
For now, I have progress with JESD204b passing most of SerDes tests (PRBS-7/23/31) and link tests (k28.5, d21.5) according to lane alarms and sync status stable HIGH.
But when running in "non-test flow" there is no output data from DAC, I mean no data at all - no matter configured as normal operation or constant single tone (0x12F 0x0001 / 0x130 0x7FFF).
My config with actual reg data is in attachment.
Thanks!
Alex
