$50

Available for immediate purchase is a one (1) CML Microcircuits DE6491 - CMX649 Codec Wireless Voice Link Demonstration Kit. This demonstration kit consists of two separate stand-alone PCBs, two headsets, and CD ROM(s) with datasheets, manuals and software. This was obtained from the insolvency of an Electronics Design company.

I have performed basic testing to verify two-way operation with the PCBs configured to use the Embedded Antenna.

The DE6491 is a CMX649-based wireless voice link demonstration kit that demonstrates CMX649 ADM Codec IC operation in a low-power, cordless headset application. Operating as a short range RF device in the 863 – 865 MHz European licence-exempt band.

Each of the stand-alone PCBs contain the following sections: CMX649-based audio, RF transceiver and control. The basic design may be user adapted to other RF frequencies. Full-duplex voice operation at up to 20 metres range is provided via a single RF channel Time Division Duplex (TDD) link. With the supplied headsets a user can investigate two-way voice-audio transfer between units. Each PCB can be powered, standalone, from a choice of AAA batteries or a bench power supply

Features:

  • Full-Duplex Wireless Voice-Link Communication Demonstration using the CMX649 ADM Voice Codec
  • Privacy via CMX649 Digital Scrambler
  • On/Off, Volume and RF Channel Pushbutton Controls
  • Operates in the 863 – 865 MHz European Licence Free Band
  • Phone Quality Voice Transmission using TDD Airlink Protocol
  • 20m Range - Line of Sight
  • Selectable RF Power

Will be well packed to ensure a safe arrival. Please note, in order to keep shipping costs as low as possible, US and International shipping does not include tracking

I am also happy to combine shipping costs with other items where possible. Feel free to request a combined shipping quote.
