C D Background This DVD design is based on ESS ES6820/22/26 single chip DVD mpeg and servo processor. The ES6820/22/26 is built upon ESS proven Programmable Multimedia Processor architecture with integrated servo DSP. A complete DVD design using ES6603 RF-Amp can support all major popular optical pickup heads. With ES68xx unify memory architecture, the whole system memory is reduced to a minimum. ES6820/22/26 provides the best price performance DVD solution in the industry and include the latest MPEG4/DivX playback capability. [email protected] System Clock Requirement ES6820/22/26 require a 27MHz clock to operate. This 27MHz can either be generated externally and feed into pin 193 and pin 195 or thru a 27MHz crystal attached to pin 193 and 194. This 27Mhz will be used for all video processing reference. In addition, internal multiplier will generate a much higher operating frequency for the internal RISC+DSP code to operate. Audio clock is generated from ES6820/22/26 by its internal PLL circuitry. SDRAM Usage ES6820/22/26 supports different SDRAM configuration from 1Mx16, 4Mx16 to 8Mx16 SDRAM. The basic requirement can go as low to 2 pcs of 1Mx16 SDRAM with standard feature set. You can also make use of 8Mx16 SDRAM to achieve longer ESP antishock time for portable application.
