Description

Audio PMC card – PMC487

The PMC487 is a single-chip PCI audio controller with integrated codec, full duplex 8 channel DAC and 2 channel ADC, 96k/16bit playback and 48k/16bit recording support.

The Integrated SPDIF transmitter can deliver 5.1 Dolby® Digital/DTS®, or 6.1/7.1 Dolby® Digital Surround EX/DTS ES soundtracks and up-to-96kHz high-definition audio stream to an external receiver.

The audio interfaces via the PMC487 front panel consist of a line input, a microphone input, a front line output and a speaker output with an on-board stereo amplifier; all using 3.5mm stereo connectors.

Optionally the audio connections can be made via the rear I/O of the PMC487 using the PIM481-J (PMC I/O Module, with four 3.5mm stereo connectors) or the PIM481-DSUB (PMC I/O Module, with 15-pin DSUB connector). The PIM481-J and PIM481-DSUB are to be mounted on a rear transition module. Both the front and rear I/O of the PMC487 are compatible with the PMC481 audio card.

A special PIM with SPDIF interface is available for the PMC487. More PIM modules may become available in the future.

The PMC487 is available in temperature range -20 .. +70°C.

Driver support for the Cmedia CMI8768-series are included in commonly used operating systems, like Windows, Linux and VxWorks.
