The DECT-Digital Circuit PMB27252 for Basestations is one of the devices of the Siemens chip set for the digital cordless telephone specified by the DECT standard.
PMB27252 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 PMB27252 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.
PMB27252 is fabricated using Siemens advanced CMOS technology and wilI be available in a 128 pin package
