ADV7604: XTAL_CTRL

Hi,

In the product data sheet for ADV7604, "ADV7604_SF_RevSpB.pdf", there is a note on page 6: "The XTAL_CTRL bit in AFE Map 0x4C[7:6] = 10b. This configures the XTAL pins for external oscillator operation. A 1.8 V oscillator must be used."

 

We use an external oscillator, so I assume we have to set this bit, but why isn't the bit documented elsewhere? Are there other settings we have to set to get optimal performance with external oscillator?

 

Regards,
