CX74016  
RF/IF Transceiver For GSM Applications  
Product Description  
Features  
• Quadrature demodulator for downconversion  
• 80 dB IF gain range and 30 dB baseband gain  
range  
• Integrated receive baseband filters with tunable  
bandwidth  
• Integrated transmit path with high phase accuracy  
• Reduced filtering requirements for the transmit path  
• Broad RF and IF range for multi-band operation  
• Integrated selectable local oscillator dividers/phase  
shifters and high/low-side injection for frequency  
plan flexibility  
The CX74016 RF/IF Transceiver is a highly integrated, monolithic device optimized  
for use in Global System for Mobile Communications (GSM) and other Time  
Division Multiple Access (TDMA) single-band or multi-band applications.  
The receive path of the device consists of three Intermediate Frequency (IF)  
amplifiers with selectable gain, an I/Q demodulator, baseband filters, DC offset  
compensation circuitry, and selectable gain baseband amplifiers.  
The transmit path of the device consists of an In-Phase and Quadrature-Phase  
(I/Q) modulator and a frequency translation loop designed to perform frequency up-  
conversion with high output spectral purity. The translation loop consists of a  
phase/frequency detector, a charge-pump, a mixer, and buffers for the required  
isolation between the RF section, Local Oscillator (LO), and IF inputs.  
• On-chip second local oscillator  
• Includes fully programmable dual-loop synthesizer  
• Selectable charge pump currents for both  
synthesizers  
In addition, the CX74016 features an on-chip dual-loop UHF/VHF frequency  
synthesizer circuit. It includes two sets of reference dividers, phase/frequency  
detectors, charge pumps, prescalers, main dividers, lock detector, and control  
circuits.  
• Digital lock detector  
• Separate enable lines for transmit, receive, and  
synthesizer modes for power management  
• 72-pin Land Grid Array (LGA) 10 mm x 10 mm  
package  
The device package and pin configuration are shown in Figure 1. A block diagram  
of the CX74016 is shown in Figure 2. The signal pin assignments and functional pin  
descriptions are found in Table 1.  
Applications  
• GSM900/DCS1800/PCS1900 digital cellular  
telephony  
• Multi-mode, multi-band terminals
