TMC22091
Overview
The TMC22x91 digital video encoders convert digital computer image or graphics data (in RGB, YCBCR, or color indexed format) or a CCIR-601 signal into a standard analog baseband television (NTSC or PAL) signal with a modulated color subcarrier. Both composite (single lead) and S-VIDEO (separate chroma and luma) formats are active simultaneously at the three analog output pins, each of which generates a standard video-level signal into doubly-terminated 75Ω load.
