Hi ADI team.

  My customer is considering to use ADV7182. ADV7182's XTALN pin is described that " In crystal mode, the crystal must be a fundamental crystal". What kind of things is cystal mode? My customer is thinking to use PLL. Is this device not able to use clock oscillator excepted crystal oscillator?

 

Also in DATAsheet, clock frequency is written 28.63636MHz typ, but clock jitter provision is not written. Clock jitter make by my customer is estimated 200ps max. Is clock jitter allowed to how long time?
