HI,everybody
Here is a problem about CVO.I'm trying to connect CVO with SAA7121 encoder(BT.656 PAL).But it does't work Normally,looks like Synchronization problems. The list following gives parameters what I use.The CLK of CVO is 27Mhz from SAA7113 's LLC PIN.Quartus 10.0 Please checking and give me a hand. Thanks a lot!

Just use the default PAL,change "Bits per pixel per color plane" to 8.Beause 4:2:2 format has 2 planes,type 3 is incorrect.
