Hi,
For a RAW-12 based camera which has DS90UB913A, we are interfacing it to a processor through DS90UB960 Deserializer. What we see is, the Sensor is outputting(checked by probing through scope) the PCLK and other Sync and data signals. We see that the PCLK detected bit is set in the Serializer side too 0xC register bit 2. Link status seems to be locked in both the Serializer and Deserializer. What we are not seeing on the Deserializer side registers 0x73 and 0x74 having proper values(its 0). Also 0x75 and 0x76 are not having values. We also do not see 0x94 and 0x95 to be changing or having values.
Can you please check the register dump attached and provide pointers on how to debug further ? Please note that when we configured the Deserializer pattern, it is working fine.
