USB Audio Controller

7 Function Description

The eKA8564A 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 button status.
