I am feeding composite PAL into my ADV7184 but it autodetects it as SECAM. If I disable autodetection and tell it it's PAL, it works fine. It also works if I disable SECAM detection by clearing the AD_SECAM_EN.SECAM bit at address 0x07.
My circuit closely follows the example circuit in the datasheet. I use a 28.63636 MHz crystal and set the EN28XTAL bit in the register at address 0x1D.
Can anyone help or make suggestions?
