OTTAWA -- Zarlink Semiconductor (NYSE/TSX:ZL) today unveiled the world's first off-the-shelf, single-chip radio transceiver (transmitter/receiver) for cell phones used in multi-band, multi-mode, 2G and 2.5G digital cellular networks.
Zarlink's ZLTM20250 chip – the industry's smallest and most flexible commercial radio transceiver – is targeted primarily at handsets for GAIT overlay networks that add GSM capability and mobile Internet data services to existing TDMA/AMPS wireless infrastructure. Multi-mode GAIT cellular networks are being deployed extensively across North America.
Zarlink's new transceiver eliminates about 60 separate components from GAIT cell phones, shrinking the size of the radio by more than half, and reducing BOM (bill of material) costs by up to 40%. The device supports high-quality reception of all GAIT voice services, as well as high-speed data services based on the 2.5G GPRS and EDGE platforms. Zarlink's is the first commercial cell phone radio that handles two-way data services at 384 Kb/s (kilobits per second) – the top EDGE rate – without using external circuitry.
"As the first commercial GAIT chip to combine receive and transmit circuitry on one piece of silicon, and the only one with full-rate duplex GPRS/EDGE, the ZL20250 offers unmatched integration and performance," said Derek Rye, cellular marketing manager, User Access business unit, Zarlink Semiconductor.
