description

The TCM4400E global system for mobile communication (GSM) baseband RF interface circuit is designed for GSM , PCS1900, and DCS 1800 European digital cellular telecommunication systems. It performs the interface and processing of voice signals, generates baseband in-phase (I) and quadrature (Q) signals, and controls the signals between a digital signal processor (DSP) and associated RF circuits. The TCM4400E includes a second serial interface for use with a microcontroller. Through this interface, a microcontroller can access all the internal registers that can be accessed through the DSP digital serial interface. This option is intended for applications in which part of the L1 software is implemented in the microcontroller. A four-pin parallel port is dedicated to the full control of the digital audio interface (DAI) to the GSM system simulator; the DAI consists of system simulator reset (SSRST) control, clock generation, and rate adaptation with the DSP. The voice processing portion of the device includes microphone and earphone amplifiers, analog-to-digital (A/D) and digital-to-analog (D/A) converters, speech digital filtering, and a serial port. The baseband processing portion of the device includes a two-channel uplink path, a two-channel downlink path, a serial port, and a parallel port. The uplink path performs Gaussian minimum shift keying (GMSK) modulation and D/A conversion, and it has smoothing filters to provide the external RF circuit with I and Q baseband signals. The downlink path performs antialiasing, A/D conversion, and channel separation filtering of the baseband I and Q signals. The serial port allows baseband data exchange with the DSP, and the parallel port controls precise timing signals. Auxiliary RF functions such as automatic frequency control (AFC), automatic gain control (AGC), power control, and analog monitoring are also implemented in the TCM4400E. Internal functional blocks of the device can be separately and automatically powered down with GSM RF windows.


These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
