ADV7611 LLC output drive

ADV7611 HDMI to parallel RGB convertor is not providing a proper LLC output. The output is not driving rail to rail and is only staying 1 to 2 volts and is sinusoidal. The part is good for 165Mhz and I'm at 150Mhz. Changing the drive strength setting to max increases the amplitude to what is shown but does not put it rail to rail. I've also tried removing the load from the LLC output and the signal did not change. I verified power on all supply inputs.
