GENERAL DESCRIPTION
In addition, the ES1878 offers I2S Zoom Video interface and support for the optional ES978 Expansion Audio Mixer in docking stations. A 4-wire expansion analog bus and 2-wire serial control bus connect the ES1878 with the ES978, allowing the ES1878 to engage the docking station’s audio resources when docked. The ES1878 AudioDrive® can record, compress, and play back voice, sound, and music with built-in mixer controls. Using two high-performance DMA channels, the ES1878 supports full-duplex operation for simultaneous record and playback. The ESFM™ synthesizer has extended capabilities within native mode operation providing superior sound and power down capabilities. The ES1878 is register compatible with Yamaha’s OPL3™ FM synthesizer. The ES1878 AudioDrive® supports ISA Plug and Play with configuration for 4 logical devices: configuration device, audio plus ESFM™, game port, and MPU-401. The ES1878 also supports an optional non-PnP (BIOS Plug and Play) configuration for the Intel® Mobile Triton chipset in which the PCA-ISA bridge features Subtractive Decode and Positive Decode Modes.
