Revision History
The current MT1379xE requires 8M bit Flash for DVD code storage & slow speed code running. For SDRAM, only 4M byte space is required. This
provides a lower cost option to use 2 pieces 1Mx16 SDRAM with 32bit data width. The other option is to use one single piece of higher density
4Mx16 SDRAM & the extra memory space will be used as track buffer for better anti-shock function.
MT1379xE only requires a single 27MHz clock to operate. This clock can either be generated externally and feed into pin 187 or thru a 27MHz crystal
attached to pin 186 and 187. This 27Mhz will be used for all video processing reference. In addition, on chip PLL circuits generate all operating
frequency for the integrated MPEG decoder RISC+DSP, Read Channel DSP+Servo circuitry, 8032 core system controller & audio clock.

This design is based on MTK second generation MT1379xE super integration DVD chipset. The MT1379xE is built upon MTK's proven previous
MT1369xE super integration chipset. It supported all MT1369xE generation features plus new features including Progressive Scan output with
built-in very high performance 6-channdel 12 bit TV-Encoder (Macrovision compliance) and Dolby ProLogic II surround sound processing. With
the chipset's highest integrity, a complete DVD design can now be implemented with minimum chip count & external components.
