Overview
The DE56 is a highly integrated, mixed-signal TeakLite® DSP-based baseband processor for digital cordless telephony and multimedia applications. The DE56 is used to develop fully integrated digital cordless telephone systems, digital answering machines, digital voice recorders (DVRs), digital baby monitors, and other audio applications.
Integrating all required digital and analog circuitry, the DE56 enables compact design at a low bill of materials (BOM) cost and small footprint. The DE56 contains two types of advanced burst-mode controller (BMC) modems for DECT (Digital Enhanced Cordless Telephone) and for the DSP Group®-proprietary EDCT (Enhanced Digital Cordless Telephone) standards to provide frequency hopping spread spectrum (FHSS) multi-handset cordless communications.
