Hi,

I have several related questions:

1) Has anyone successfully encoded colour PAL 8-bit YCrCb (EAV/SAV) input to CVBS out using the ADV7390? By successfully I mean with colour correctly displayed, with no horizontal or vertical cropping of the image.

I so, please let me know what your register settings were, I have tried the settings in the datasheet and others beside without success! 

2) After doing a software reset by writing to register 0x17, is it safe to assume all registers are at their reset values if a read of reg 0x17 returns 0x00 - and that it is therefore safe to write to the other setup registers ?

3) Are there any special tricks to getting the ADV7390 to output the Black Bars Test Pattern correctly?

 

Thanks in anticipation.
