CM8828 can be built in the home audio electronics or personal computer to provide high fidelity sound and become a professional audio processing center in your life.
CM8828 + CM9882A
High Performance PCI Express Audio Processor
Overview
The PCI express HD CM8828 is a high quality multi-channel audio processor that not only an Intel HD Audio specification compatible audio single chip, but also can be a controller which can link HDA codec. CM8828 can be built in the home audio electronics or personal computer to provide high fidelity sound and become a professional audio processing center in your life.
It supports up to 10 outgoing channels and 6 ingoing channels. The 10 outgoing channels are composed of 2 playback DMA's, which are multi-channel DMA (24 bits, 8 channels, 192k), Headphone out & S/PDIF (each 24 bits, 2 channels, 192k), and RTC (real-time communication) DMA (24 bits, 2 channels, 192k). The 6 ingoing channels are spread in 3 recording DMA's (up to 24 bits, 192k).
