2 GENERAL DESCRIPTION
The PCD5041 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
handset products which comply with the following
standards (and updates):
• 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 PCD5041 has interfaces to:
• ADPCM CODECs in the handset mode
• A radio transceiver; the interface is fully decoded, and
includes power-down signals
• An external microcontroller.
The PCD5041 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.
