1. GENERAL DESCRIPTION
1.1 ES680X Vibratto-II CL DVD Processor DESCRIPTION
The ES6809 Vibratto™II CL processor is a single chip DVD system on chip with DivX®, MPEG-4, and DVD video playback. The ES6809 integrates all front-end DVD servo control functions including read channel, ECC, servo DSP, MCU for high performance disc read and a high quality TV encoder for a brilliant 480p/576p progressive scan video output with Macrovision™ copy protection. The ES6809 is an ideal solution for stand-alone DVD players, DVD receivers, DVD/VCR combos and DVD A/V minicomponent systems. The ES6809 is built on the ESS proprietary dual CPU Programmable Multimedia Processor (PMP) core consisting of 32-bit RISC and 64-bit DSP processors that deliver the best DVD feature set. This PMP core, common through out all generations of Vibratto DVD products, allows for easy migration from previous ESS based designs. The processing units enable simultaneous parallel execution of system commands and data processing to perform specialized encoding and decoding tasks. The vector engine performs audio and video processing to support MPEG, Dolby®, DTS™, JPEG and DivX standards. The front-end servo control of the ES6809 supports all popular optical pick-up units (OPU). Its high performance error handling allows for playback of scratched and fingerprinted media. The ES6809 has a unified memory architecture for both the front-end servo control and backend decoder to achieve the lowest possible system memory cost. The ES6809 has unmatched audio features including an integrated high quality stereo audio digital to analog converter (DAC) and an analog to digital converter (ADC). Additionally, the ES6809 supports DVD-Audio, CD-DA, HDCD, MP3, WMA, AAC, Dolby ProLogic™ II digital audio formats and Karaoke. The ES6809 CL DVD processor with DTS support is offered with the ES6809D, which has the same pinout as the standard ES6809. The ES6809 and ES6809D processors are in 208-pin Plastic Quad Flat Pack (PQFP) device package.

1.2 MEMORY
1.2.1 System SRAM Interface
The system SRAM interface controls access to optional external SRAM, which can be used for RISC code, stack, and data. The SRAM bus supports four independent address spaces, each having programmable bus width and wait states. The interface can support not only SRAM, ROM/EPROM and memory-mapped I/O ports for standalone applications are also supported.
1.2.2 DRAM Memory Interface
The Vibratto-II CL provides a glueless 16-bit interface to DRAM memory devices used as
video memory for a DVD player. The maximum amount of memory supported is 16 MB of Synchronous DRAM (SDRAM). The memory interface is configurable in depth to support 128-Mb addressing. The memory interface controls access to both external SDRAM or EDO memories, which can be the sole unified external read/write memory acting as program and data memory as well as various decoding and display buffers.
1.3 FRONT PANEL
The front panel is based around an VFD and a common NEC (or compatible) front panel controller chip, (uPD16311). The ES6809/ES6908 controls the uPD16311 using several control signals, (clock, data, chip select). The infrared remote control signal is passed directly to the ES680X for decoding.

3. Audio Interface
The audio interface is a bidirectional serial port that connects to an external audio ADC/DAC for the transfer of PCM (pulse coded modulation) audio data in I2S format. It supports 16-, 24-, and 32-bit audio frames. No external master clock is required. The ES680X offers three audio interface modes:
1. Stereo mode using TSD0 pin 120.
2. Dolby Digital (AC-3) 5.1 channel mode using TSD[3:0] pins 120, 121, 124, and 125.
3. Dolby Digital (AC-3) 5.1 channel mode using S/PDIF pins 102 and 103. AV2500/2600 Has also 5.1 channel Class-D amplifier outputs 5 x 4 ohms satelites and 1 x 8
ohms subwoofer.
4. Audio Performance
Table 36 lists the audio performance characteristics of the digital audio processor of the ES6809 under normal operating conditions (AVCC = 3.3V ?10%, DVCC =2.5?10%, TAMB 0 to 70?C).

5 VIDEO INTERFACE
Video Display Output
The video output section controls the transfer of video frames stored in memory to the internal TV encoder of the Vibratto. The output section consists of a programmable CRT controller capable of operating either in Master or Slave mode.
The video output section features internal line buffers which allow the outgoing luminance and chrominance data to match the internal clock rates with external pixel clock rates, easily facilitating YUV4: 2:2 to YUV4: 2:0 component and sample conversion. A polyphase filter achieves arbitrary horizontal decimation and interpolation.
Video Bus The video bus has 8 YUV data pins that transfer luminance and chrominance (YUV) pixels in CCIR601 pixel format (4:2:2). In this format, there are half as many chrominance (U or V) pixels per line as luminance (Y) pixels; there are as many chrominance lines as luminance.
Video Post-Processing
The Vibratto video post-processing circuitry provides support for the color conversion, scaling, and filtering functions through a combination of special hardware and software. Horizontal up­sampling and filtering is done with a programmable, 7-tap polyphase filter bank for accurate non-integer interpolations. Vertical scaling is achieved by repeating and dropping lines in accordance with the applicable scaling ratio.

Video Timing
The video bus can be clocked either by double pixel clock and clock qualifier or by a single pixel clock. The double clock typically is used for TV displays, the single for computer displays.
6 SDRAM MEMORY
The ES680X provides a glueless 16-bit interface to DRAM memory devices used as video memory for a DVD player. The maximum amount of memory supported is 16 MB of Synchronous DRAM (DRAM). The memory interface is configurable in depth to support 128-Mb addressing.
Typical SDRAM Configurations:
The memory interface controls access to both external SDRAM or EDO memories, which can be the sole unified external read/write memory acting as program and data memory as well as various decoding and display buffers. At high clock speeds, the Vibratto memory bus interface has sufficient bandwidth to support the decoding and displaying of CCIR601 resolution images at full frame rate.
7 FLASH MEMORY
The decoder board supports AMD class Flash memories. Currently 4 configurations are supported:
FLASH_512K_8b FLASH_1024K_8b FLASH_512Kx2_8b FLASH_512Kx2_16b
The Vibratto permits both 8- and 16-bit common memory I/O accesses with a removable storage card via the host interface.
8 SERIAL EEPROM MEMORY
An I2C serial EEPROM is used to store user configuration (i.e. language preferences, speaker setup, etc.) and software configuration.. Industry standard EEPROM range in size from 1kbit to 256kbit and share the same IC footprint and pinout. The default device is 2kbit, 256kx 8, SOIC8 SGS Thomson ST24C02M1 or equivalent.

9 Digital Servo Controller
The digital servo includes an internal DSP, on-chip RAM and ROM, control logic, a loader interface, a serial interface, and an on-chip ADC-DAC, and interfaces with the MCU. The MCU handles the high-level functions of optical disk and front-end system control. The interface between the servo controller and the MCU is illustrated in the Figure.
11 FRONT PANEL
VFD CONTROLLER
The VFD controller is a NEC uPD16311. This controller is not a processor, but does include a simple state machine which scans the VFD and reads the front panel button matrix. The 16311 also includes RAM so it can store the current state of all the VFD icons and segments. Therefore, the 16311 need only be accessed when the VFD status changes and when the button status is read. The ES6808/ES6809 can control this chip directly using PIO pins or can allow the front panel PIC to control the VFD.
12 RESET CIRCUITRY & VOLTAGE REGULATORS
Two different chips are supported to provide the power-on-reset DS1811 or AAT3520. (optional) Voltage regulators:
U11: LM1117(1.8V) For 2V PLL power supply
U12: 7805 For 5V power supply
U13: LM1117(3.3V) For 3.3V power supply
