Mixed Signal Device for GSM and GPRS Applications
The CX20524 Mixed Signal Device (MSD) is a highly integrated device designed for use in multi-band Global System for Mobile communications (GSM) and General Packet Radio Service (GPRS) handsets. The MSD includes all the power management, voice-band, mixed signal, and radio control functions required in a GSM/GPRS handset and module. In the receive path, the MSD digitizes the baseband In-Phase/Quadrature (I/Q) inputs. Digital samples are then sent to the Baseband Processor (BP) via the Rx serial interface. The receive path features a programmable gain amplifier (PGA) for Automatic Gain Control (AGC) of the receive signal. In the transmit path, bursts of digital data are input to the MSD over the control port. A Gaussian……
