eKA8565A
USB Audio Controller
1 General Description
The eKA8565A is a USB digital audio controller with audio data processing that
supports 16-bit 2-channel format at 48kHz, 44.1kHz, 32kHz or 8kHz sampling rate.
The device has an integrated USB transceiver, USB core, MCU, DAC, ADC, and I2S
Input/Output. It can handle a high-level USB protocol, and manages user interface via
HID I/O pins.
