TVP5146PFP
TEXAS INSTRUMENTS TVP5146PFP 芯片, 视频解码器, 10位, 30MSPS, HTQFP-80
The is a high quality, single-chip Digital Video Decoder that digitizes and decodes all popular baseband analog video formats into digital component video. The TVP5146 decoder supports the analog-to-digital conversion of component RGB and 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 four 10-bit 30MSPS analog-to-digital 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 10 video input terminals can be configured to a combination of RGB, YPbPr, CVBS or S-video video inputs.
