Qualcomm Incorporated (NASDAQ: QCOM) today announced the introduction of the CSM2000, a next-generation Cell Site Modem for Code Division Multiple Access (CDMA) infrastructure and test equipment. The CSM2000 is a multiple-channel CDMA digital baseband modem capable of supporting up to eight forward link channels and eight reverse link channels. CDMA infrastructure manufacturers will benefit from a significant cost reduction per channel, a very large reduction in the circuit board space required, as well as lower power consumption per channel.

"The new CSM2000 device enables design of much smaller, lower cost CDMA base stations. The 8x integration allows a single CSM to demodulate up to eight simultaneous channels as required for IS-95B high speed data services and supported by MSM3000," said Johan Lodenius, vice president of marketing for Qualcomm's ASIC Products Division.

The CSM2000 incorporates eight channel elements into a single device. Each channel element performs CDMA modulation, CDMA demodulation and Viterbi decoding. The channel elements are chained together internally requiring only one set of transmit outputs and therefore reducing the drive power required per channel. The high integration of the CSM2000 allows substantial power savings over previous CSM devices. The CSM2000 provides more than 75 percent power savings when replacing eight CSM1.0 devices and more than 25 percent power savings when replacing eight CSM1.5 devices. The CSM2000 requires a single power supply operating between 2.7 and 3.6 volts.

The CSM2000 contains improved time tracking and lock detect circuitry in the demodulator of each channel element. This design enhancement providesup to 1.2 dB improvement over CSM1.0 and CSM1.5 depending on vehicle speedand the number of fingers combining at a given time. It also reduces theoutput power required from the phone, resulting in longer battery life andincreased reverse link system capacity.

Each channel element within the CSM2000 can be accessed as if it were a single CSM1.0 or CSM1.5. The registers are shared between channel elements whenever possible. These features allow the CSM2000 to be software compatible with the CSM1.0 and CSM1.5 with very minor changes.

The CSM2000 comes in a 128-pin Metric Quad Flat Pack (MQFP) package allowing a significant space savings for base station hardware. The footprint of a single CSM2000 is only 18 percent of the area occupied by eight CSM1.5 devices.

"It is very important for us to continue to support CDMA infrastructure andtest equipment manufacturers with higher efficiency parts fornext-generation base stations and testers. The CSM2000 provides a leap in both integration and cost efficiency," said Don Schrock, president of Qualcomm's ASIC Products Division.

Engineering samples are expected to be available in the third quarter of 1998 with production quantities expected in the fourth quarter of 1998.
