Hi,

 

I am using ADV7610 and ADV7513 devices for HDMI Receiver and transmitter.

 

1. I am using TPD12S520 from TI for ESD Protection in HDMI Receiver. It has separate pins for Input and output lines of CEC. I want to know where should I use the Diode+ 27K resistor pull-up resistor (At the input of ESD protection IC or at the output of it). 

 

2. I am using TPD12S016 from TI for ESD Protection in HDMI Transmitter. It has separate pins for input and output lines of CEC. Also, There is a 10K pullup at input and 26K pullup at output of CEC lines. Can you please confirm if Diode + 27K pull up is still required? Also, If required, where should I place it? (At the input of ESD protection IC or at the output of it)
