GENERAL DESCRIPTION
SAA2510
· EBU audio output, fully transparent from input to output in CD-DA mode and generated in MPEG mode · Downloadable microcode for internal controllers · Internal video timing generator · Requires 40 MHz crystal for system clock generation · Requires 27 MHz crystal or external 27 MHz source for video timing generation · Requires 16.9344 MHz (384 × 44.1 kHz) clock locked to CD drive · Internal generation of 90 kHz MPEG clock · Capability of sharing external DRAM by 3-stating all DRAM pins.
MPEG1 audio and video CD (VCD) decoder, intended for use in low-cost dedicated video CD players. When used with a 4 Mbit DRAM and a digital video encoder, the decoder adds the required functionality to a CD decoder to implement a low-cost video CD player capable of playing discs coded to version 2.0 of the video CD specification. The SAA2510 is an I2C-bus controlled chip and features serial data input in four common bus formats. It provides digital video output in CCIR601 and 656 formats. A bit-mapped on-screen display is provided and output video timing can be 525 lines/30 frames per second or 625 lines/25 frames per second. The chip is microcode programmable for feature enhancement.
