TVP5150AM1: TVP5150: Jitter on all Sync and Interrupt lines

Part Number: TVP5150AM1
Other Parts Discussed in Thread: TVP5150


i built my own PCB with the TVP5150 to run this with an STM32F407. The comunication over I2C is ok and i can write/read all registers. I configuered a default setup for the TVP5150 and execute this on a EvalBoard of the TVP5150 successfully. On the EvalBoard i don't have a jitter on the HSYNC, VSYNC and INT lines. Also the StatusRegister1 returns 0x6e.

EvalBoard is one of this: 

My own built PCB has a jitter after activating the lines with miscellaneous register. You can see the lines HSYNC, VSYNC and input line in the images down below. The result of the StatusRegister1 is 0x61. How can it be and how can i fix it? The input signal between EvalBoard and my own PCB is the same.

Thanks for your help
