ADV3202 - cropped video signals

Hello everybody,

 

I have a problem using the ADV3202. All output video signals are cropped at about 900 mV in a manner, that no sync is transmitted. VPOS is connected to +5 V, VNEG is connected to GND, VREF is supplied with 2.5 V and VCLAMP is connected to GND as well. (I tried several connections for VCLAMP and VREF, but neither worked)

 

Attached I have a snippet of the schematic and a sample of input and output video signal.

 

Can you please give me a hint to solve this problem? Thanks in advance.
