THE BASE-BAND SECTION
6.1.1.
INTRODUCTION (SEE Fig. 17)
The base-band section consists ofa base-band integrated circuit (BBIC), a Flash PROM and an EEPROM.
6.1.2.
THE BASE-BAND INTEGRATED CIRCUIT (BBIC)
The CICB00001367 (PMB5737 : IC6) is a CMOS device designed to handle all the audio, signal and data processing needed
in a DECT base unit. It contains a "burst mode controller" which takes care ofDECT specific physical layer and radio section
control. It also contains an ADPCM codec filter used for speech encoding and decoding in the DSP section, a general purpose
microcontroller, various other ADC´s, DAC´s, timers and power control circuitry.

The BBIC interfaces to its external PROM (IC5) via a data/address/control bus. It connects to the EEPROM (IC9) via a serial
interface, and a second serial interface is used during manufacture and service to connect to an external computer.
