Leading design groups and cellular silicon companies are readying a version of the DigRF physical interface standard for third generation (3G) handsets. The DigRF defines the physical interface between the baseband and radio ICs inside mobile terminals, allowing any combination of supporting chipsets.

The main proponents behind the Digital Interface Working Group are TTPCom, Agere Systems, Infineon Technologies, Motorola, Philips, Renesas, RF Micro-Devices, Silicon Laboratories, Skyworks and Sony Semiconductor Devices Europe.

Version 1.12 of the DigRF standard covers GSM, GPRS and Edge (classes 1 to 12) and is available for download.

The DigRF Working Group was established in 2002 by companies who recognized the benefit of creating an interface standard, as chip set designs move away from the analog I/O interface, that had become the de facto standard, to an all-digital interface between baseband and RF.

The standard has been made available for IC designers to use and the group expects DigRF will become the commonly accepted interface definition for next-generation chip sets.
