Abstract

A GSM Base Transceiver Station (BTS) subsystem combines all the functions needed to modulate or demodulate the downstream and upstream wireless signals of the GSM system. The mixed-signal ASIC is implemented in a standard 3.3V CMOS 0.5/spl mu/m process. It functions as a baseband analog front-end located between the control and data framing CPU and the RF section of the BTS. The chip embeds all the functions of the baseband GMSK/EDGE modulator, the transmitting power regulation, various analog biasing and sensing features, two programmable phase-locked loops (PLL), a synchronization timer, and other digital controlling features.
