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).
