1 Introduction
The TVP5150A device is an ultralow power NTSC/PAL/SECAM video decoder. Available in a space saving 32-pin
TQFP package, the TVP5150A decoder converts NTSC, PAL, and SECAM video signals to 8-bit ITU-R BT.656
format. Discrete syncs are also available. The optimized architecture of the TVP5150A decoder allows for
ultralow-power consumption. The decoder consumes 115 mW of power in typical operation and consumes less than
1 mW in power-down mode, considerably increasing battery life in portable applications. The decoder uses just one
crystal for all supported standards. The TVP5150A decoder can be programmed using an I2C serial interface. The
decoder uses a 1.8-V supply for its analog and digital supplies, and a 3.3-V supply for its I/O.
The TVP5150A decoder converts baseband analog video into digital YCbCr 4:2:2 component video. Composite and
S-video inputs are supported. The TVP5150A decoder includes one 9-bit analog-to-digital converter (ADC) with 2x
sampling. Sampling is ITU-R BT.601 (27.0 MHz, generated from the 14.31818-MHz crystal or oscillator input) and
is line-locked. The output formats can be 8-bit 4:2:2 or 8-bit ITU-R BT.656 with embedded synchronization.
The TVP5150A decoder utilizes Texas Instruments patented technology for locking to weak, noisy, or unstable
signals. A Genlock/real-time control (RTC) output is generated for synchronizing downstream video encoders.
Complementary 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
industry standard I2C serial interface. The TVP5150A decoder generates synchronization, blanking, lock, and clock
signals in addition to digital video outputs. The TVP5150A decoder 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 TVP5150A decoder detects copy-protected input signals according to the Macrovision
standard and detects
Type 1, 2, 3, and colorstripe pulses.
