具有强大可靠的同步检测器的超低功耗 NTSC/PAL/SECAM 视频解码器
The device is an ultralow-power NTSC/PAL/SECAM video decoder. Available in a space-saving 48-terminal PBGA package or a 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 power under typical operating conditions 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 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 luminance and chrominance data paths to reduce both cross-luminance and cross-chrominance artifacts; a chrominance trap filter is also available.
Video characteristics including hue, 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 processes.
The main blocks of the TVP5150AM1 decoder include:
and SECAM B, D, G, K, K1, L Video
Automatic Gain Control AGC for Best Signal-to-Noise S/N Performance
and Cross-Chrominance Noise Reduction
for Unique VBI Data Signals
