GENERAL DESCRIPTION

The Z87200 is a programmable single-chip, spread-spectrum, direct-sequence transceiver. The Z87200 incorporates Stanford Telecom spread-spectrum and wireless technology and is identical to Stanford Telecoms STEL- 2000A. By virtue of its fast acquisition capabilities and its ability to support a wide range of data rates and spreadspectrum parameters, the Z87200 spread-spectrum transceiver supports the implementation of a wide range of burst data communications applications.

FEATURES

■ Complete Direct Sequence Spread-Spectrum Transceiver in a Single CMOS IC

■ Programmable Functionality Supports Many Different Operational Modes

■ Acquires Within One Symbol Duration Using Digital PN Matched Filter

■ Two Independent PN Sequences, Each up to 64 Chips Long for Distinct Processing of the Acquisition/Preamble Symbol and Subsequent Data Symbols

■ Power Management Features

■ Optional Spectral Whitening Code Generation

■ Full- or Half-Duplex Operation

Benefits

■ High Performance and High Reliability for Reduced Manufacturing Costs

■ Ideal for a Wide Range of Wireless Applications Including Data Acquisition Systems, Transaction Systems, and Wireless Local Area Networks (WLANs)

■ Fast Response and Very Low Overhead when Operating in Burst Modes

■ Allows High Processing Gain to Maximize the Acquisition Probability, then Reduced Code Length for Increased Data Rate

■ Reduced Power Consumption

■ Randomizes Data to Meet Regulatory Requirements

■ Permits Dual Frequency (Frequency Division Duplex) or Single Frequency (Time Division Duplex) Operation

■ Small Footprint, Surface Mount
