Description

The TVP5158, TVP5157, and TVP5156 devices are 4-channel high-quality NTSC/PAL video decoders that digitize and decode all popular base-band analog video formats into digital video output. Each channel of this decoder includes 10-bit 27-MSPS A/D converter (ADC). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and applies the gain.

Composite input signal is sampled at 2x the ITU-R BT.601 clock frequency, line-locked alignment, and is then decimated to the 1x pixel rate. CVBS decoding uses five-line adaptive comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also available. On CVBS inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain is included.

All four channels are independently controllable. These decoders share a single clock input for all channels and for all supported standards.

TVP5158 provides a glueless audio and video interface to TI DaVinci video processors. Video output ports support 8-bit ITU-R BT.656 and 16-bit 4:2:2 YCbCr with embedded synchronization. TVP5158 supports multiplexed pixel-interleaved and line-interleaved mode video outputs with metadata insertion. TVP5158 and TVP5157 integrate 4-Ch audio ADCs to reduce the BOM cost for surveillance market. Multiple TVP5158 devices can be cascade connected to support up to 8-Ch Video or 16-Ch audio processing.

Noise reduction and auto contrast functions improve the video quality under low light condition which is very critical for surveillance products.

The TVP5158, TVP5157, and TVP5156 can be programmed by using a single I2C serial interface. I2C commands can be sent to one or more decoder cores simultaneously, reducing the amount of I2C activity necessary to configure each core. This is especially useful for fast downloading modified firmware to the decoder cores.

TVP5158, TVP5157, and TVP5156 use 1.1-V, 1.8-V, and 3.3-V power supplies for the analog/digital core and I/O. These devices are available in a 128-pin TQFP package.
