Product Descriptions

The TVP5147M1 device is a high-quality, single-chip digital video decoder that digitizes and decodes all popular baseband analog video formats into digital component video. The TVP5147M1 decoder supports the analog-to-digital (A/D) conversion of component YPbPr signals, as well as the A/D conversion and decoding of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes two 11-bit 30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and applies a programmable gain and offset. A total of ten video input terminals can be configured to a combination of YPbPr, CVBS, or S-video video inputs.

Composite or S-video signals are sampled at 2× the ITU-R BT.601 clock frequency, line-locked alignment, and are then decimated to the 1× 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 and S-video inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I 2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain is included, as well as a patented chroma transient improvement (CTI) circuit.

The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr.

The TVP5147M1 decoder generates synchronization, blanking, field, active video window, horizontal and vertical syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and programmable logic I/O signals, in addition to digital video outputs.
