Product Summary

The CX20524-15 is a mixed signal device for GSM and GPRS applications. The CX20524-15 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 of the CX20524-15 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 of the CX20524-15 features a programmable gain amplifier (PGA) for Automatic Gain Control (AGC) of the receive signal.

Features

CX20524-15 features: (1)Auxiliary 8-bit ADC for monitoring system signals; (2)3 V/1.8 V SIM card interface; (3)Temperature sensor; (4)High speed asynchronous serial ports for interface to Skyworks Baseband Processor device; (5)Low speed asynchronous serial port for power management functions; (6)Voltage regulators for both internal (fixed voltage) and system (programmable voltage) needs; (7)Low power operation; (8)Control circuit for multi-chemistry advanced battery charger; (9)Power-On Reset (POR) generation; (10)Over current-limiting; (11)Power On/Off control inputs.
