CX74063

RF Transceiver for Multi-Band GSM/GPRS/EDGE Applications with

Integrated Crystal Oscillator and Power Ramping Controller

The CX74063 transceiver is a highly integrated device for multi-band Global

System for Mobile Communications™ (GSM™) or General Packet Radio Service

(GPRS) applications. The device requires a minimal number of external

components to complete a GSM radio subsystem. The CX74063 supports

GSM850, EGSM900, DCS1800, and PCS1900 applications. The receiver also

supports downlink Enhanced Data-Rate GSM Evolution (EDGE).

The receive path implements a direct down-conversion architecture that eliminates

the need for Intermediate Frequency (IF) components. The CX74063 receiver

consists of three integrated Low Noise Amplifiers (LNAs), a quadrature

demodulator, tunable receiver baseband filters, and a DC-offset correction

sequencer.

In the transmit path, the device consists of an In-phase and Quadrature (I/Q)

modulator within a frequency translation loop designed to perform frequency up-

conversion with high output spectral purity. This loop also contains a phase-

frequency detector, charge pump, mixer, programmable dividers, and high power

transmit Voltage Controlled Oscillators (VCOs) with no external tank required. With

the integrated gain controller (and an integrator ), the device realizes the Power

Amplifier Control (PAC) functionality when combined with a coupler, a Radio

Frequency (RF) detector and a Power Amplifier (PA).

The CX74063 also features an integrated, fully programmable, sigma-delta

fractional-N synthesizer suitable for GPRS multi-slot operation. Except for the loop

filter, the frequency synthesizer function, including a wideband VCO, is completely

on-chip. The reference frequency for the synthesizer is supplied by the integrated

crystal oscillator circuitry.

The CX74063 is available as a 56-pin RFLGA™ 8x8 mm package. Package

dimensions are shown in Figure 1.
