ADF4350ABCPZ-RL7

The ADF4350ABCPZ-RL7 is a wideband phase-locked loop (PLL) frequency synthesizer with an integrated voltage-controlled oscillator (VCO) from Analog Devices. It operates as either a fractional-N or integer-N synthesizer, offering output frequencies from 137.5 MHz to 4400 MHz. The device features a fundamental VCO range of 2200 MHz to 4400 MHz and programmable output dividers of 1, 2, 4, 8, and 16 to generate lower frequencies. Typical RMS jitter is less than 0.4 ps rms, ensuring clean clock generation for demanding applications.

Key electrical specifications include a supply voltage range of 3.0 V to 3.6 V, logic compatibility at 1.8 V, and CMOS input logic levels. The synthesizer incorporates a low phase noise VCO, programmable dual-modulus prescaler, and cycle slip reduction for fast lock times. Additional features include RF output mute function, 3-wire serial interface, and analog/digital lock detect.

The ADF4350ABCPZ-RL7 is suitable for wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), test equipment, wireless LANs, CATV equipment, and clock generation applications. It is offered in a 32-lead LFCSP (Lead Frame Chip Scale Package) with surface mount termination and is available in tape and reel packaging.
