The ADV7180 series 10-bit 4x Oversampling SDTV Video Decoder which automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL and SECAM standards into 4:2:2 component video data compatible with the 8-bit ITU-R BT.656 interface standard. External HS, VS and FIELD signals provide timing references for LCD controllers and other video ASICs, if required. Three analog video input channels accept standard composite, S-Video or component video signals, supporting a wide range of consumer video sources. AGC and clamp-restore circuitry allow an input video signal peak-to-peak range to 1.0V. The line-locked clock output allows the output data rate, timing signals and output clock signals to be synchronous, asynchronous or line locked even with ±5% line length variation. Mini-TBC functionality provided by adaptive digital line length tracking, signal processing and enhanced FIFO management.
