ADF4350BCPZ

The ADF4350BCPZ by Analog Devices Inc. is a versatile wideband frequency synthesizer featuring an integrated Voltage Controlled Oscillator (VCO). This component supports both fractional-N and integer-N phase-locked loop (PLL) synthesizer implementations when paired with an external loop filter and reference frequency.

Key electrical specifications include an impressive output frequency range from 137.5 MHz to 4400 MHz. The integrated VCO itself operates from 2200 MHz to 4400 MHz. The device provides programmable divide-by-1/2/4/8/16 circuits, enabling the generation of lower RF output frequencies. It boasts low phase noise and a typical RMS jitter of less than 0.4 ps.

Operational parameters include a power supply range of 3.0 V to 3.6 V and logic compatibility at 1.8 V. The ADF4350BCPZ offers programmable output power, a programmable dual-modulus prescaler (4/5 or 8/9), and an RF output mute function that is both pin- and software-controllable. Control is managed via a simple 3-wire serial interface. Additional features include analog and digital lock detect, switched bandwidth fast-lock mode, and cycle slip reduction.

Applications for the ADF4350BCPZ span wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), test equipment, wireless LANs, CATV equipment, and general clock generation. The device is suitable for designs requiring precise frequency control and low noise.
