6.1.2 THE BASE-BAND INTEGRATED CIRCUIT
(BBIC)
TOP PREVIOUS NEXT
The 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 of DECT 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 via a serial interface, and a second serial interface is used during manufacture and service to
connect to an external computer.
It connects to Serial Flash ROM via serial interface.
