CS4955

CS4954 CS4955 NTSC/PAL Digital Video Encoder Features Description l Six DACs providing simultaneous composite, S-video, and RGB or Component YUV outputs l Programmable DAC output currents for low imped-ance (37.5 Ω) and high impedance (150 Ω) loads. l Multi-standard support for NTSC-M, NTSCJAPAN, PAL (B, D, G, H, I, M, N, Combination N) l ITU R.BT656 input mode supporting EAV/SAV codes and CCIR601 Master/Slave input modes l Programmable HSYNC and VSYNC timing l Multistandard Teletext (Europe, NABTS, WST) support l VBI encoding support l Wide-Screen Signaling (WSS) support, EIA-J CPX1204 l NTSC closed caption encoder with interrupt l CS4955 supports Macrovision copy protection Version 7 The CS4954/5 provides full conversion from digital video formats YCbCr or YUV into NTSC and PAL Composite, Y/C (S-video) and RGB, or YUV analog video. Input formats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or ITU R.BT656 with support for EAV/SAV codes. Video output can be formatted to be compatible with NTSC-M, NTSCJ, PAL-B,D,G,H,I,M,N, and Combination N systems. Closed Caption is supported in NTSC. Teletext is supported for NTSC and PAL. Six 10-bit DACs provide two channels for an S-Video output port, one or two composite video outputs, and three RGB or YUV outputs. Two-times oversampling reduces the output filter requirements and guarantees no DAC-related modulation components within the specified bandwidth of any of the supported video standards. Parallel or high-speed I2C compatible contr...
