The TVP5158IPNP is a 4-channel high-quality NTSC/PAL Video Decoder that digitize and decode all popular base-band analog video formats into digital video output. Each channel of this decoder includes 10bit 27MSPS analog-to-digital 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. TVP5158 provides a glueless audio and video interface to TI DaVinci™ video processors.
