    Hi Pavan,

    This device will not support 29.4912Mhz crystal oscillator because as mentioned in below section of datasheet:

    Crystal period should be in between 50 to 200ns seconds only. That means if you convert into frequency then the frequency should be in between 5Mhz to 20Mhz only. So, we should not give more than 20Mhz crystal to this device.
