When using the TVP5146M2I over the industrial (
40°C to 85°C) temperature range, the following register
writes are required following device power up and RESETB to write 0x14 to VBUS register 0xA00014.
This setup is optional when using the TVP5146M2 over the commercial (0
°C to 70°C) temperature range.

Adjusting External Syncs
The proper sequence to program the following external syncs is:
To set NTSC, PAL-M, NTSC 443, PAL60 (525-line modes):
– Set the video standard to NTSC (register 02h).
– Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h).
To set PAL, PAL-N, SECAM (625-line modes):
– Set the video standard to PAL (register 02h).
– Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h).
For autoswitch, set the video standard to autoswitch (register 02h).
