ESCRIPTION

The Squeak 1.5 WHAM2 (Wireless HiFi Audio Module) is a
highly integrated module package that provides a complete
solution for wireless audio. Squeak 1.5, using the Micro Linear
ML2724 radio transceiver front end and the XInC2 wireless
processor, is ideal for high performance wireless audio
applications such as home theater, stereo and outdoor
speakers, and microphones. Squeak 1.5 is available in either a
25 or 50 meter indoor range WHAM2 module.

The WHAM2 digitizes a 2-channel stereo input signal, sends it
across a robust 2.4 GHz radio frequency link, and converts the
signal back to a stereo analog signal for use at a remote
location. WHAM2 is also available with a Digital Audio Serial
Interface (DASI) port that can be configured to interface with
any SPI supporting device (I

2

S, left- or right-justified), including

ADCs, DACs, digital audio streams such as S/P-DIF or USB. A
development kit is required to modify the DASI port and/or to
modify application source code firmware.
