I’m reviewing the “ADV7513 Hardware User Guide” and I have several questions:
1] I am looking for a complete set of reference schematics and PCB layout example.
2] If I am not using the Audio inputs, can I tie them to ground (through a 0R resistor) ?
SPDIF, I2S[3:0], MCLK, LRCLK, SCLK
3] If I am not use the CEC feature , can I tie both CEC and CEC_CLK to ground (through a 0R resistor)?
4] What is the recommended trace impedance when routing the parallel RGB bus?
I’m was thinking of using 50 ohms.
