CS8553 Datasheet | Myson Technology

DESCRIPTION The CS8553 provides full conversion from digital video format YCb Cr into NTSC/PAL posite. It can be used in VCD, DVD, and digital VCR applications. Two times oversampling reduces the output filter requirements and guarantees no alias interference by internal UV filters and Y filter. A 9-bit DAC provides a posite video output with high quality image. 32-pin package and pin assignment make the CS8553 patible with major vendors. w w w .D at a S e e h U 4 t . m o c TV Encoder FEATURES - Especially designed for VCD, Karaoke, digital VCR, DVD, DIGITAL set-top box. - Supports the following 4 modes: NTSC, PAL-M, PAL-BDGHI, PAL-Nc. - 8-bit 4:2:2 YCb Cr inputs for glueless interface to MPEG decoders. - CVBS (posite YC) outputs. - Supports CCIR-601 format, non-square pixel - 2x oversampling simplifying external filtering. - 6MHz and 1.3MHz anti-alias filters for Y and U/V channels each. - 1 channel of 9-bit DAC. - Supports master and slave modes. - Supports interlace operation only. - Automatic mode detection/switching in slave mode. - 3.3V supply voltage; 5V tolerant for all digital I/O pins.
