[ADV7513] DE, Hsync, and Vsync Generation Recommended Settings for 1920x1080@30/25

Category: Datasheet/Specs
Product Number: ADV7513

Hello,

In the ADV7513 programming guide, the tables for setting the DE generation, sync adjustment and embedded sync processing (i.e. tables 26, 27, & 28) do not show the settings for both 1080p25 nor 1080p29/30. 

I'd like to know these recommended settings.

Please check if the register settings I tried are correct.

* (Table 26) Register Settings for DE Generation

0x35 0x36 0x37 0x38 0x39 0x3A
1080p29/30 0x2F 0xE9 0x0F 0x00 0x43 0x80
1080p25 0x2F 0xE9 0x0F 0x00 0x43 0x80

* (Table 27) Register Settings for Sync Adjustment

0xD7 0xD8 0xD9 0xDA 0xDB 0x17[6:5]
1080p29/30 0x16 0x02 0xC0 0x10 0x05 0x0
1080p25 0x84 0x02 0xC0 0x10 0x05 0x0

* (Table 28) Register Settings for Embedded Sync Processing

0x30 0x31 0x32 0x33 0x34 0x17[6:5]
1080p29/30 0x16 0x02 0xC0 0x08 0x05 0x0
1080p25 0x84 0x02 0xC0 0x08 0x05 0x0

Any help is significantly appreciated.
