Pocatello, ID--March 24, 1997--American Microsystems Inc. (AMI; Pocatello, ID) unveiled the newest additions to their WavePlex family of wireless ICs.
The SX049 Spread Spectrum Transceiver, the SX048 Spread Spectrum Receive-Only, and the SX047 Spread Spectrum Transmit-Only are the first direct sequence spread spectrum (DSSS) ICs developed by AMI specifically for higher data rate wireless applications.
Security systems, subway train platform monitors, remote medical systems, and oil and mining applications are a few of the data, voice, and video applications that will benefit from these high data rate baseband solutions.
The SX049 is a high data rate transceiver containing all the baseband circuitry needed to implement DSSS radios. It offers data rates from 100 bps to 16 Mbps, and PN code lengths up to 2,047 chips per bit.
Designed to serve as a collection host for a large group of WavePlex transmitters and transceivers, the SX048 features data rates up to 16 Mbps.
Offering data rates up to 8 Mbps, the SX047 is designed to interface easily with other WavePlex receivers and transceivers. Multiple SX047 nodes can supply data to a single collector host.
Available in a 52-lead PQFP package, the SX047 Transmit-Only IC allows the user to manage internal transmit functions including the type and length of PN codes, data rates, chipping rates, preamble, transmission protocols, power levels and type of redundancy checks, as well as manage the external circuitry for signal transmission.
The SX049 Transceiver and SX048 Receive-Only ICs are available in 68-lead PLCC, 64-lead PQFP, and 64-lead TQFP packages. These baseband ICs feature message processor receive circuits including the receive PN code generator, receive synchronization and tau-dither tracking loop, integrate dump control, data descrambler, packet decoder, and CRC checker.
Each PN code generator consists of two 11-bit PN generators, allowing selection of an "A" code, a "B" code, or a "Gold code" combination of the "A" and "B" codes. These baseband ICs can be programmed and interfaced through a standard 8-bit microcontroller port and have port FIFOs to ease data timing on transmission and reception.
Samples of the SX049 will be available this month, with volume production scheduled for May 1997. Samples and volume production for the SX047 and SX048 will follow. Volume pricing, for quantities of 10,000 pieces, is currently projected at $23.05 per unit for the SX049, $14.65 for the SX048, and $8.80 per unit for the SX047.
