Silicon Laboratories Inc. has announced the availability of the Aero+ GSM/GPRS transceiver that integrates a digitally-controlled crystal oscillator (DCXO) and eliminates the need for a VC-TCXO, reducing board space and component count in mobile phones.

The addition of the DCXO enables handset developers to use low-cost crystal resonators instead of larger and more expensive VC-TCXO modules. The transceiver also integrates the IF SAW filter, external LNA, transmit and RF VCO modules, and more than 60 other discrete components.

The Aero+ is also claimed to offer compatibility with current baseband subsystems, thus minimizing modifications to existing automatic frequency control algorithms to preserve prior software investments.

As with its predecessor, the transceiver provides a software programmable universal baseband interface allowing handset designers to implement the Aero+ with any baseband subsystem. The Aero+ is fully-compliant with GPRS Class 12 requirements providing high-speed data communications to the mobile computing environment.

The Aero+ transceiver includes: 32-lead MLP Si4200 transceiver, 20-lead Si4201 baseband interface, and 32-lead MLP Si4134T RF synthesizer. The Aero chipset is offered at $5.80 in quantities of 10,000.
