CM6210
Multi-channel USB-I2S Audio Controller
DESCRIPTION
The CM6210 is a USB 2.0 full-speed/high-speed audio
processor that supports the latest USB Audio Device
Class V1.0. The CM6210 provides industry-standard
HDA and I2S I/O interfaces, supports a maximum of 8
channels of output and 2 channels of input, and also
integrates a 96KHz/24-bit S/PDIF transmitter, making
it very versatile.
Furthermore, the CM6210 has an embedded 8051
microprocessor that can enhance the flexibility and
functionality with external upgradeable ROM codes.
The CM6210 is the most powerful audio core for your
multi-channels audio products.
