Introduction
2.1
Description
The TVP5150 device is an ultralow-power video decoder for NTSC and PAL video signals. Available in a space
saving 32-pin TQFP package, the TVP5150 device converts NTSC and PAL video signals to 8-bit ITUR
BT.656 format. Discrete syncs are also available. The optimized architecture of the TVP5150 device allows
for ultralow-power consumption. The device consumes 113 mW of power in typical operation and consumes
less than 1 mW in power-down mode, considerably increasing battery life in portable applications. The device
uses just one crystal for all supported standards. The TVP5150 device can be programmed using an I2C serial
interface. The device uses a 1.8-V supply for its analog and digital supplies, and a 3.3-V supply for its I/O.
The TVP5150 device converts baseband analog NTSC and PAL video into digital YUV 4:2:2 component video.
Luminance/chrominance (Y/C) composite and S-video inputs are also supported. The TVP5150 device
includes one 9-bit A/D converter with 2x sampling. Sampling is ITUR BT.601 (27.0 MHz, generated off the
14.318-MHz crystal or oscillator input) and is line-locked for correct pixel alignment. The output formats can
be 8-bit 4:2:2 or 8-bit ITUR BT.656 with embedded synchronization.
The TVP5150 device utilizes Texas Instruments patented technology for locking to weak, noisy, or unstable
signals. A chroma frequency control output is generated for synchronizing downstream video encoders.
Complementary 3-line or 4-line adaptive 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, brightness, saturation, and sharpness may be programmed
using the I2C high speed serial interface. The TVP5150 device generates synchronization, blanking, field,
lock, and clock signals in addition to digital video outputs. The TVP5150 device includes methods for
advanced vertical blanking interval (VBI) data retrieval. The VBI data processor slices, parses, and performs
error checking on Teletext, Closed Caption, and other data in several formats.
The TVP5150 device detects copy-protected input signals according to the Macrovision
7.1 standard.
