FUNCTIONAL DESCRIPTION
The PCD509x is a family of single-chip controllers, designed for use in Digital Enhanced Cordless Telecommunications
systems (DECT). The family is designed for minimum component-count and minimum power consumption. All controllers
include an embedded 80C51 microcontroller with on-chip memory and I
2
C-bus. The Philips DECT RF interface is
implemented. The Burst Mode Logic (BML) performs the time-critical MAC layer functions for applications in DECT
handsets and base stations. The ADPCM transcoding is in compliance with the CCITT recommendation G.721 and
includes receive and transmit filters.
