TVP5150AM1ZQCR

Product Summary

The TVP5150AM1ZQCR is an ultralow power NTSC/PAL/SECAM video decoder. The TVP5150AM1ZQCR is an ultralow power NTSC/PAL/SECAM video decoder. Available in a space saving 32-pin TQFP package, the TVP5150AM1ZQCR 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 TVP5150AM1ZQCR 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 TVP5150AM1ZQCR 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 TVP5150AM1ZQCR decoder converts baseband analog video into digital YCbCr 4:2:2 component video. Composite and S-video inputs are supported. The TVP5150AM1ZQCR 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 TVP5150AM1ZQCR 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.
