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.
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.
