Customer have a question regarding ADV7511 DDC I2C timing. According to I2C_BUS_SPECIFICATION Rev 2.1, the
min. "Set-up time for a repeated START condition" (tSU;STA) should be 4.7us, but the measured data on ADV7511 is 4.2us. Customer wants to know why?
I have attached the measured DDC I2C waveform and mark the area of tSU;STA.
