Hi ADI engineers
I am using your ADV7612 and ADV7511 on my board. The ADV7612's crystal is 28.63636MHz. After I config the IC ,I want to test the crystal whether it works right. When I use the probe to detect the pin of the crystal XTAL_P,the waveform from the crystal disappear and so does the LLC.
Does the Schematics and PCB have something wrong ? The C201 and C202 is the C_load.
And even when the crystal oscillator works "well"(I am not sure because I can not detect it), I can usually get a blue 480p screen. The ADV7612 never decode the TMDS right(I have config the chip by your ADV7612-VER.3.0c.txt). Is it possible that the crystal oscillator causes the problem ?
