Preliminary Datasheet AV6301

Wireless Audio Sender IC

General Description

The AV6301 / 6302 chipset is optimized for building
wireless gaming headsets and point to multi-point
audio distribution solutions such as rear speakers
and subwoofers in home theater systems..The
chipset is comprised of two ICs: AV6301 (sender)
and AV6302 (client). These devices share the VMI
RF Protocol and may be mixed and matched with
other VMI chips (AAV6200, V6201, and AV6202).

The AV6301 / 02 chipset achieves the goal of
enabling a single core design to service multiple
game platforms (PC or Console), External Digital
Signal Processing (DSP) is also easily supported
for all gaming platforms.

The chip set provides all functions necessary to
complete a bidirectional wireless audio link with
high quality voice and music performance.
Operation in the worldwide 2.4 GHz spectrum
addresses the need for global application.

Chipset

AV6301

The AV6301 is a highly integrated, single-chip,
wireless audio sender IC. It integrates the following: a
complete 2.4 GHz RF transceiver, PHY & MAC,
advanced power management hardware, audio DSP,
USB 2.0 transceiver and a full complement of
programmable digital interfaces to support a wide
range of end-product user-interface requirements,
including SPI and TWI interfaces.

The device incorporates a complete USB 2.0
transceiver and enumerates as a USB Audio device
as well as USB Human Interface Device (HID) without
the need for external drivers, enabling true plug &
play. Additionally, the device makes available 3
independent I2S interfaces, allowing independent
processing of non-USB audio sources. Simultaneous
use of the USB and I2S ports is enhanced by
additional audio processing capability, allowing for
independent control and mixing of the different audio
sources.

AV6301 Features

9 Advanced Signal Routing Capability

9 USB Port Enumerates as Audio and / or

Human interface device (HID)

9 Three available I2S ports

9 Simultaneous operation of USB and I2S

ports

9 Expansive Digital I/O Capability

9 20 General Purpose Input / Output Pins

9 Master and Slave SPI and TWI interfaces

9 Pulse Width Modulated (PWM) I/O support

9 Straightforward implementation of external

EEPROM, DSP, Audio Codec and Host uC for
advanced applications

9 On-Chip One-Time-Programmable (OTP)

Memory

Applications

PC Game Wireless Headset

Game Console Wireless Headset

I2S based Wireless Audio

Wireless Rear Speakers
