AWR2243: CSI Deskew calibration function

KenF

Part Number: AWR2243

Hi Experts,

My customer is building their own cascade board with AWR2243 and their back-end chip. They have some questions about CSI calibration.

1) Does AWR2243 (CSI Tx) have Deskew calibration function? (i.e. Should their back-end chip (CSI Rx) support Deskew calibration function?)
2) If (1) is yes, when does the function work? For instance, in initialization phase, periodically, etc)
3) If (1) is yes, Is it possible to execute it manually by issuing AWR command/API?

Best regards,
Ken

For the AWR2243 cascade setup we use FPGA bridge for VIP to CSI2. The FPGA bridge(lattice) has to match the CSI settings of AWR side.

Hi Abhed,

Thank you for your reply. But I don't think it answers their questions. Can you please answer (1)~(3) above?

Best regards,
Ken

Hi Ken,

AWR2243 Doesn't have any de-skew calibration function or support. This is something which the host may do if needed. As I said earlier the settings of CSI2 need to match at AWR and host side.
