GENERAL DESCRIPTION

The Z87010/Z87L10 is a second generation CMOS Digital Signal Processor (DSP) that has been ROM-coded by Zilog to provide full-duplex 32 Kbps, Adaptive Delta Pulse Code Modulation (ADPCM) speech coding/decoding (CODEC), and interface to the Z87000/Z87L00 Spread Spectrum Cordless Telephone Controller. Together the Z87000/Z87L00 and Z87010/Z87L10 devices support the implementation of a 900 MHz frequency-hopping spread spectrum cordless telephone in conformance with United States FCC regulations for unlicensed operation.
