As per data-sheet , Nominal Frequency of crystal oscillator should be 28.63636 MHz. Also it is given that " If an external 1.8V, 28.63636 MHz clock oscillator source is used to clock the ADV7280A , the output of the oscillator is fed into the XTALN pin ". FPGA clock wizard is able to generate 28.636MHz clock. Can i use this as input clock to XTALN pin. Kindly share documents where external clock is used for ADV728x series decoder.
