terawins T515A

The T515A is a low-power mixed signal SDTV Video Decoder that provides major cost saving solution for the LCD applications. With built-in high performance Dual ADCs, Chroma Phase Locked Loop, Automatic Sync Tip Slicer and 2-D Comb Filter, T515 can separate Luma and Chrom signal as true as no cross luma and cross chroma effects. With effective signal demodulator, Cb/Cr data can be obtained from Chroma signal. ITU-R BT.656 data or 8 bit 4:2:2 data with sync signal are selected as data output.
