1 Introduction
The TVP5040 is a high-quality single-chip digital video decoder that converts base-band analog National Television
System Committee (NTSC) and phase alternating line (PAL) video into digital component video. Both composite and
S-video inputs are supported. The TVP5040 includes two 10-bit A/D converters with 2x sampling. Sampling is
square-pixel or ITU-R BT.601 (27 MHz) and is line-locked for correct pixel alignment. The output formats can be 8-bit,
10-bit, 16-bit, or 20-bit 4:2:2, and 8-bit or 10-bit ITU-R BT.656 with embedded synchronization. The TVP5040 utilizes
Texas Instruments patented technology for locking to weak, noisy, or unstable signals, and a chroma frequency
control output is generated for synchronizing downstream video encoders.
Complementary three-line adaptive (2-H delay) comb filtering is available for both the luma and chroma data paths
to reduce both cross-luma and cross-chroma artifacts; a chroma trap filter is also available. Video characteristics
including hue, contrast, and saturation may be programmed using one of five supported host port interfaces; I2C,
three parallel host interface (PHI) modes, and VIP. The TVP5040 generates synchronization, blanking, field, lock and
clock signals, in addition to digital video outputs.
The TVP5040 includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor
slices, parses, and performs error checking on teletext data in several formats. A built-in FIFO stores up to 14 lines
of teletext data, and with proper host port synchronization full-screen teletext retrieval is possible. The VBI data
processor also retrieves closed-caption data. The TVP5040 can also pass through double-sampled raw composite
data for host-based software VBI processing.
The main blocks of the TVP5040 include:
Analog processors and A/D converters
Y/C separation
Chrominance processor
Luminance processor
Clock/timing processor and power-down control
Output formatter
Host port interface
VBI data processor
