A B C D E DVA620 REV-A2 ES60X8 + 8051 + PT2320 Layout---------RUTHERFORD REV-A1B1 4 4 Background Revision History This DVD design is based on ESS third generation ES60X8 single chip DVD processor. The ES60X8 is built upon ESS proven Rev-A1 Programmable Multimedia Processor architecture with various speed enhancement and optimization. It supported all features we 1.Base on FYEMANN-A1B1,add PT2320,add MCU,add output. developed from previous generation chip plus new features including DVD-Audio (with built-in CPPM logic), built-in TV-Encoder (Macrovision compliance) and support Progressive Scan output. With the advance of ES60X8 integration, a complete DVD Rev-A2 design can now be implemented with minimum external components.

This 27MHz can either be generated externally and feed into pin 105 or thru a 27MHz crystal attached to pin 49 and 50. 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 ES60X8 by its internal PLL circuitry. SDRAM Usage ES60X8 support the use of higher density 4Mx16 SDRAM. This is the prefered choice for simplier design and lower memory cost. The current DVD code requires only 2Mx16 memory size to operate. This provide an option to use cheaper half-bank 4Mx16 SDRAM. The design has put into consideration to support this type of half-bank SDRAM. 3
