In one our designs we are using ADV7391 for camera applications.
We are able to generate NTSC internal colour test pattern with the following DAC register setting.
0x00 = 0x10
0x01 = 0x00
0x80 = 0x10
0x82 = 0xCB
0x84 = 0x40
When we are trying to generate PAL colour internal test partern we are getting black and white bars in monitor Please suggest.
0x80 = 0x11
0x8C = 0xCB
0x8D = 0x8A
0x8E = 0x09
0x8F = 0x2A
Please find the attached PAL Test pattern captured on scope and Black and white pattern getting on monitor
Please cross check your 0x02 sub-address configuration in Page29 and also refer Table45 for with different input/output for SD color space conversion.
Kindly refer the reference configuration script for PAL in Page92, to verify the PAL color internal test pattern.
