ES1869 AudioDrive® Solution Product Brief
DESCRIPTION
The ES1869 AudioDrive® solution is a single, mixed-signal chip that adds 16-bit stereo sound and FM music synthesis to personal computers. It is compliant with the Microsoft® PC 97 and PC 98 specification and WHQL audio requirements. The ES1869 possesses an embedded microcontroller, OPL3TM superset ESFMTM music synthesizer, 16-bit stereo wave ADC and DAC, 16-bit stereo music DAC, MPU-401 UART mode serial port, dual game port, full Plug and Play support, CD-ROM IDE interface, hardware master volume control, two serial port interfaces to external DSP and external wavetable music synthesizer, I2S Zoom Video interface, DMA control logic with FIFO, and ISA bus interface logic. There are three stereo inputs (typically line, CD audio, and auxiliary line) and a mono microphone input. All of this on a single chip that can be designed into a motherboard, add-on card, or integrated into other peripheral cards such as Fax/Modem, VGA, LAN, I/O, etc. The ES1869 AudioDrive® solution can record, compress, and play back voice, sound, and music with built-in mixer controls. It supports full-duplex operation for simultaneous record and playback using two DMA channels. The ESFMTM synthesizer has extended capabilities within native mode operation providing superior sound and power-down capabilities. It is a register compatible superset to the OPL3 FM synthesizer. The ES1869 AudioDrive® solution supports the full ISA Plug and Play standard. It provides Plug and Play configuration for logical devices: audio, ESFMTM synthesizer, game port, MPU-401, IDE CD-ROM, MODEM, and an additional user defined device. The MPU-401 serial port is for interfacing to an external MIDI device. The integrated 3-D audio effects processor uses technology from Spatializer® Audio Laboratories, Inc. and expands the sound field emitted by two speakers to create a resonant 3-D sound environment. The speakerphone application can be implemented either by digital interface through the DSP serial port, or by analog interface through Mono-In and Mono-Out. A DSP serial interface in the ES1869 allows an external DSP to take over ADC or DAC resources. The ES1869 AudioDrive® solution supports telegaming architecture with headsets and includes data paths for host-based Acoustic Echo Cancellation processing. Advanced power management features include suspend/resume from disk or host-independent self-timed power-down and automatic wake-up. The ES1869 is compliant to the ACPI standard. It is available in industry-standard 100-pin Plastic Quad Flat Pack (PQFP) and Thin Quad Flat Pack (TQFP) packages.

AC-coupled externally to CIN_L and CIN_R to remove DC offsets. These outputs have internal series resistors of about 5k ohms. Capacitors to analog ground on these pins can be used to create a low-pass filter pole that removes switching noise introduced by the switched-capacitor filters. Capacitive coupled inputs, left and right. These inputs have internal pull-up resistors to CMR of approximately 50k ohms. Line inputs, left and right. LINE_L and LINE_R have internal pull-up resistors to CMR. Line-level stereo outputs, left and right. Can drive a 10k ohm load. Modem interrupt enable active-low input. Generated from the modem UART. PC speaker analog output. Modem interrupt request active-high input. Normally low digital PC speaker input. This signal is converted to an analog signal with volume control and appears on analog output PCSPKO. Left/right strobe for I2S interface. This pin has a pull-down. Output from ES1869 for the modem CSB. If selected by the PnP logic, pin 56 becomes an active-high chip select for external general-purpose device.
