ADV7513 input timing

Hello all,

Is there any specification about input signal timing of ADV7513 ?
Does ADV7513 need input of PCLK or data before register settings ?

Our customer's system configuration is below two.

Case which ADV7513 does not output video signal
  ADV7513 power on -> REST release from Micon -> register setting (I2C) -> input PCLK and data to ADV7513

Case which ADV7513 outputs video signal
  ADV7513 power on -> REST release from Micon ->  input PCLK and data to ADV7513 ->register setting (I2C)

Regards,
