USB Audio Controller

7 Function Description

The eKA8566A is a USB Audio Controller that transmits/receives audio data stream to /

from the host through its Audio Streaming interface. The Audio Data Format supports

16-bit, 2-channel, and 48kHz, 44.1kHz, 32kHz, 8kHz PCM. It has three interfaces.

Interface 1 supports four sampling frequencies. The sampling rate is changed by

FS_SEL0 and FS_SEL1. For Interface 2, this device transmits data at a rate that is

locked to frame timing. When user uses the recording format (ex. 8kHz) to record

speech other than 48kHz stereo format, the application software will transform 48kHz

data to 8kHz data. Interface 3 is HID pipe which is used to read user data.

The EKA8566A defines a PSTN + Skype protocol to communicate with an external

MCU. The device can use the protocol to by pass USB vendor data to external MCU or

read data from external MCU to USB host.
