hello,
Problem description: We use a product of the deserializer DS90UB948-Q1. When the customer uses it, the picture flickers.
When the problem occurs, by reading and printing the value of the 948 register, compared with the normal 948 register value,
only the register value of the address 0xA2 has changed, from 8c to 7d.
Screenshot of normal value:
Screenshot of abnormal value:
1.Why can't I find this register 0xA2 in the specification?
2.What does the change of this value mean?
3.Could the accidental phenomenon in the figure below be possible that the signal is interfered,Can it be solved if the output voltage swing is increased?
Output voltage swing configuration register 0x4B is 0
thanks!
