Description
TVP5150AM1-EP
Ultralow-Power NTSC/PAL/SECAM Video Decoder
SLES213 – MAY 2008
www.ti.com
The TVP5150AM1 device is an ultralow-power NTSC/PAL/SECAM video decoder. Available in a
space-saving 32-terminal TQFP package, the TVP5150AM1 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 TVP5150AM1 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
TVP5150AM1 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 TVP5150AM1 decoder converts baseband analog video into digital YCbCr 4:2:2 component video.
Composite and S-video inputs are supported. The TVP5150AM1 decoder includes one 9-bit
analog-to-digital converter (ADC) with 2
× 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 TVP5150AM1 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 four-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 TVP5150AM1 decoder generates synchronization,
blanking, lock, and clock signals in addition to digital video outputs. The TVP5150AM1 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 TVP5150AM1 decoder detects copy-protected input signals according to the Macrovision standard
and detects Type 1, 2, 3, and colorstripe pulses.
The main blocks of the TVP5150AM1 decoder include:
Robust sync detector
ADC with analog processor
Y/C separation using four-line adaptive comb filter
Chrominance processor
Luminance processor
Video clock/timing processor and power-down control
Output formatter
I2C interface
VBI data processor
Macrovision detection for composite and S-video
