Could you please let us know an answer for our query?
We designed a video hardware which used ADV7189B with X'tal 28.63636MHz.
We turn on the hardware. After that, we observed the following outputs.
LLC2 pin :14.3MHｚ
LLC1 pin :28.63MHｚ
When we are checking those pins, we do not initialize internal registers of ADV7189B.
After that, we set the EN28XTAL bit from 0 to 1. we observed that those pins output the following frequencies.
LLC2 pin : 13.5MHz
LLC1 pin : 27MHz
Is our experience correct?
