XVF3510-UA - FOR USB ACCESSORY VOICE INTERFACE APPLICATIONS
The XVF3510-UA variant includes the same audio infrastructure as the XFV3510-INT, but it includes a
USB interface that implements a UAC1.0 audio device to interface to the host system. The USB
interface also supports an Endpoint 0 control channel and a USB HID to signal input events to the
host.
The system architecture of the XVF3510-UA is shown below.

NOTE: The XVF3510-UA product also supports a hybrid mode of operation where the reference signal
is delivered via I2S rather than USB. This mode is selected via modification of the configuration data
stored in the flash device.
