CX74016 Datasheet

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 upconversion 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.

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.

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.
