Other Parts Discussed in Thread: DS90UB954-Q1, DS90UB936-Q1
Hello Team,
I got some questions from customer about DS90UB935-Q1.
Q. Is there any way to check the 935 working correctly? Generally we can check it from PASS, LOCK pin of Deserializer, or BIST function from Deserializer.
But customer want to check if the 935 working correctly without via Deserializer. Is there any method?
("Working correctly" means that SOC send the CSI-2 data to 935, then 935 transfer the correct signal to Deserializer based on CSI-2 data.)
Q. In the 32 bit PACKET HEADER(PH), Is there any bit to indicate the pixel size? I'm not familiar with the CSI-2 format. If you know the good material to understand CSI-2 format, I'd like to know.
Q. Regarding with 0x61, 0x62, 0x63 and 0x64, these registers are notification of PACKET HEADER information, Do the registers notify the header information which comes from SoC to 935?
Or Do the registers notify the header information which is transferred from 935 to Deserializer?
Thanks,
Yuta Kurimoto
