I'm playing with LM1881 (video sync separator). The problem I encountered is that the chip does not generate 2 signals. Status of my tests is as follows:
1. I can see VSYNC and burst signals
2. I can't see HSYNC and Even/Parity signals.
Is #2 indication of damaged chip or I just can not operate oscilloscope?
I tested 2 chips with PAL video source and scenario is the same.
