Background Revision History
This DVD design is based on ESS ES6820/22/26 single chip DVD mpeg and servo processor. The ES6820/22/26 is Rev-A1
built upon ESS proven Programmable Multimedia Processor architecture with integrated servo DSP. A complete DVD Base on SMITH-A2B2'S design
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 Rev-A2
DVD solution in the industry and include the latest MPEG4/DivX playback capability. 1.Add R202,R203,R204,R205 for B,D swap option.
[email protected] 2.Add pull low resistor R206 to AMPSTBY.
3.Delete the connection from CE to FOCUS;delete the connection from RFENV to SLED.
System Clock Requirement 4.Change R59,R62,Q7,Q8,Q9 to open;change R60 to 0 ohm.
ES6820/22/26 require a 27MHz clock to operate. This 27MHz can either be generated externally and feed into pin 193 5.Revise the pickup configure table,add R43,R51,RR6,RR8 option,only 502W is confirmed.
and pin 195 or thru a 27MHz crystal attached to pin 193 and 194. This 27Mhz will be used for all video processing 6.Change R201 to open;add a pull low resistor option to HOMESW.
reference. In addition, internal multiplier will generate a much higher operating frequency for the internal RISC+DSP 7.Change R77 to 6.8K.
code to operate. Audio clock is generated from ES6820/22/26 by its internal PLL circuitry.
8.Modify the two channel circuit(add 74HCT174),modify the filter parameter.
9.Change DV342 to default pickup.
SDRAM Usage 10.Change R63 from 33K to 56K;short D9;R206 from 4.7K to 3.3K.
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 11.Change R45 and R46 from 4.7K to open.
longer ESP antishock time for portable application. 12.Change C3,C4 from 27pf to 22pf.
13.Change U24 to 74ACT174.
