TI TVP5150PBS

The TVP5150AM1 device is an ultra-low-power NTSC/PAL/SECAM video decoder. Available in a space-saving 48-pin PBGA or 32-pin TQFP package, the decoder converts NTSC, PAL, and SECAM video signals to 8-bit ITU-R BT.656 format, with support for discrete sync signals. The optimized architecture of the TVP5150AM1 decoder achieves ultra-low power consumption. Under typical operating conditions, the decoder consumes 115mW, dropping to less than 1mW in power-down mode, significantly extending battery life in portable applications. The decoder uses a single crystal for all supported standards. The TVP5150AM1 decoder is programmable via an I²C serial interface.

The TVP5150AM1 decoder converts baseband analog video to digital YCbCr 4:2:2 component video, supporting composite and S-Video inputs. It includes a 9-bit ADC with 2× oversampling. Sampling conforms to ITU-R BT.601 (27.0 MHz, generated from a 14.31818 MHz crystal or oscillator input) and is line-locked. The output format can be 8-bit 4:2:2 or 8-bit ITU-R BT.656 with embedded sync.

The TVP5150AM1 decoder employs Texas Instruments' patented technology to lock onto weak, noisy, or unstable signals. It generates a sync/real-time control (RTC) output for synchronizing downstream video encoders.

Both the luma and chroma data paths provide complementary four-line adaptive comb filtering to reduce luma crosstalk and chroma crosstalk artifacts, along with a chroma notch filter.

Video characteristics including hue, brightness, saturation, and sharpness are programmable via the industry-standard I²C serial interface. In addition to digital video output, the TVP5150AM1 decoder generates sync, blanking, lock, and clock signals. The decoder features advanced vertical blanking interval (VBI) data retrieval. The VBI data processor performs slicing, parsing, and error checking on teletext, closed caption, and several other data formats.

The TVP5150AM1 decoder detects Macrovision copy-protected input signals and identifies Type 1, Type 2, Type 3, and color stripe processing per the Macrovision standard.
