TVP5154
4-CHANNEL LOW-POWER PAL/NTSC/SECAM VIDEO DECODER
WITH INDEPENDENT SCALERS AND FAST LOCK
SLES163A – MARCH 2006 – REVISED JULY 2006
The output formatter is responsible for generating the output digital video stream. The YCbCr digital output
can be programmed as 8-bit 4:2:2 or 8-bit ITU-R BT.656 parallel interface standard. Depending on which
output mode is selected, the output for each channel can be unscaled data, scaled data, or both scaled
and unscaled data interleaved in various ways.

External (discrete) syncs are provided via the following signals:
VSYNC (vertical sync)
FID/VLK (field indicator or vertical lock indicator)
GPCL/VBLK (general-purpose I/O or vertical blanking indicator)
PALI/HLK (PAL switch indicator or horizontal lock indicator)
HSYNC (horizontal sync)
AVID (active video indicator)
VSYNC, FID, PALI, and VBLK are software set and programmable to the CLK pixel count. This allows any
possible alignment to the internal pixel count and line count. The default settings for a 525-/625-line video
output are shown in Figure 4-1.
