Selecting oscillator ADV7280A-M

Category: Hardware
Product Number: ADV7280A-M

Hi,
I'm using ABM11-28.63636MHZ-D2X-T3 as the ADV7280A-M oscillator.
Is this oscillator fit the device requirments?

The 100 Ohm part may work but you will probably have to change the load caps.  You can only 100% verify what the new load caps are when you have the final board to test with.

Tolerance is good.  The schematics normally use a 30Ohm crystal.  You may have to tweak the load caps or change to a low series resistance crystal.

  • Hi,

    At the ABM11-28.63636MHZ-D2X-T3 data sheet the ESR is 100 ohm. Is it OK?

    What's the load caps and series resistance values?

    The goal is to get the crystal to spin and maintain tolerance over temp.  Here's an app note on our video crystal oscillators.

  • Hi,

    I didn't understand. Can I use ESR 100ohm for the ADV7280A-M?
