DECT Digital Circuit for Basestations

PMB 27251/2

General Description

Type

Package

P-TQFP-128-1 (SMD)

The DECT-Digital Circuit for Basestations is one of the

devices of the Siemens chip set for the digital cordless

telephone specified by the DECT standard.

PMB 27251/2

Features

The device designed for single cordless fixed stations is a

highly integrated circuit and realizes most of the system

functions needed in such an equipment. The circuit contains

a digital signal processor, an 8-bit 80C51-compatible

microcontroller and the burst mode controller. Furthermore

the circuit handles the interfacing of the different components

of the DECT chipset.

• 8-bit µC with integrated ROM/RAM

• 32 bit/s ADPCM-transcoder

• Digital filtering and gain stages

• Echocancellation

• Burst mode controller

• Internal calls possible

• Power supply voltage: 5 V ± 5 %

• Low power consumption

• Advanced low power CMOS technology

• Encryption

The device is fabricated using Siemens advanced CMOS

technology and wilI be available in a 128 pin package.

• PMB 27251: 6 K RAM

• PMB 27252: 64 K ROM, 4 K RAM
