2 GENERAL DESCRIPTION
The PCD5043 DECT Burst Mode Controller (BMC) is a
custom IC that performs the DECT Physical Layer and
MAC Layer time-critical functions, for use in DECT remote
radio transceiver (PABX) products which comply with the
following standards:
• DECT CI part 2: Physical layer (DE/RES 3001-2)
• DECT CI part 3 : Medium Access Control layer
(DE/RES 3001-3)
• DECT CI part 7: Security features for DECT
(DE/RES 3001-7)
• DECT CI part 9: Public Access Profile
(DE/RES 3001-9).
The PCD5043 has interfaces to:
• Up to 4 ADPCM CODECs in a simple base station (with
up to 4 analogue lines) without glue logic
• n x 64 kbits/s highway, where n = 1 to 32, for systems
requiring more than 4 connections to the network
• A radio transceiver; the interface is fully decoded, and
includes power-down signals
• An external microcontroller.
The PCD5043 is designed to be connected to an ADPCM
CODEC (Philips’ PCD5032, for example) and an
80C51-type microcontroller. Other microcontrollers (e.g.
68000) and CODECs can also be supported.
