Plextek develops software for Analog Devices ISM transceiver chips

Software package enables customers to reduce product time-to-market

Cambridge, 8th June 2005: Plextek has developed the ADIismLink software package for Analog Devices' ADF702x range of monolithic ISM (Industrial Scientific and Medical) band transceivers. The software provides a flexible framework within which customers can develop real world applications. It also provides the capability for Analog Devices to demonstrate and customers to evaluate the radio solution. This is significant for application developers, saving them time and development effort and enabling customers to get their products to market more quickly.

Analog Devices ADF702x family of ISM transceivers are aimed primarily at low power, short-range telemetry and control applications, such as plant monitoring, alarms, security and remote control. They can operate at data rates from approximately 2 kbps to 115 kbps with a corresponding impact on usable range.

The ADIismLink software saves the customer significant time and development effort by taking care of the radio (air interface) protocol and the application programming framework (an elementary operating system). The protocol enables data to be reliably delivered between network endpoints and a single base station whilst abiding by the legislative rules and restrictions that apply to the frequency band in use. Most ISM bands have a tight limit on the transmit duty-cycle and/or require frequency hopping. The operating system aspects of the software are strongly geared towards power saving. All system and user-application processes are managed together so that microcontroller sleeping can be dynamically optimised.

The software package (protocol and application framework) is available now from Analog Devices as part of the development platform for the ADF702x family of ISM transceivers. More information is available through ADI's website at http://www.analog.com. Plextek will continue to work with Analog Devices on custom modifications of the core functionality or further development of the application software.
