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. System / Chipset Features
Stereo audio path: >93 dB SNR, 20 kHz BW
Mono voice path: >70 dB SNR, 6.5 kHz voice Sophisticated audio routing and mixing options to meet demands of multiple gaming headset platforms Over-the-air (OTA) serial interface: >2 kbps, bi-directional, full duplex Works within 3 inches of WIFI Client without impairment to Audio or WIFI throughput Advanced forward error correction coding, error detection, and audio-specific error concealment Diversity antenna support Low and Fixed Latency: <16 ms, Long Range: 15m (non-line-of-site) Auto search/sync/standby/wake-
up/shutdown
All Voltage Regulators on-chip
Interoperability with VMI (AV6201 / 02) Chipset is a highly transceiver and a AV6301 The AV6301 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 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

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified.
