Product Summary

The TVP5147M1PFP is a Flexible Output Formatter. The TVP5147M1PFP is 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 4 channels are independently controllable. These decoders share a single clock input for all channels and for all supported standards. The applications of the TVP5147M1PFP include Security/surveillance digital video recorders/servers and PCI products, Automotive infotainment video hub, Large format video wall displays and Game systems.
