Hi ,
I am using TVP5150 in a Frame Grabber design. Input provided to TVP5150 is in composite video format. Output is configured to 8-bit 4:2:2 YCbCr. This video is fed to FPGA for YCbCr to RGB conversion and displayed on lcd monitor though VGA.
Problem which I am facing in this design is, there is lot of noise viewed on the display. When I select the test pattern in FPGA, there is no such noise found. But when I select the video from TVP5150 noise is included as shown in the picture below.
. 
Expected output is
Following are the registers configured in TVP5150
Miscellaneous Controls Register(0x03) : 0xAF
Auto-switch Mask Register(0x04) : 0xC0;
Outputs and data rates select(0x0D) : 0x40 ;
Configuration Shared Pins Register(0x0F) : 0x02 ;
Kindly guide me in configuring the device to avoid the noise.
Here is Schematics for your reference
Thanks,
Pradeep Reddy
