Other Parts Discussed in Thread: DS90UH927Q-Q1,
Hi Expert,
My customer have an issue about HDCP blue display during short period (around 0.2sec)
It seems to be retry automaticaly betwee SER and DES devices.
Also, It was occered with DS90UH928Q-Q1 and DS90UH927Q-Q1.
They can control deserializer side only, due to serializer side is black box. (They cannot control serializer side. )
They can use I2C back channel for monitoring some registers. The MCU in serializer side is master and the MCU in deserializer side is slave.
They read HDCP status register, it have always been OxC4(HDCP Status) : 0x01.
It seems to show HDCP Authenticated.
Could you please give me your advice about how to analize behavier and solving this issue?
Thanks
Muk
