ADF4350BCPZ

The ADF4350BCPZ from Analog Devices is a versatile wideband frequency synthesizer featuring an integrated Voltage Controlled Oscillator (VCO). This component is designed for implementing fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when paired with an external loop filter and reference frequency.

Key electrical specifications include an impressive output frequency range spanning from 137.5 MHz to 4400 MHz. The integrated VCO itself operates with a fundamental output frequency between 2200 MHz and 4400 MHz. The device offers 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.

Designed for flexibility, the ADF4350BCPZ operates with a power supply range of 3.0 V to 3.6 V and supports 1.8 V logic compatibility. It includes programmable dual-modulus prescalers (4/5 or 8/9), programmable output power levels, and an RF output mute function that is both pin- and software-controllable. Control is managed via a simple 3-wire serial interface. Analog and digital lock detect features are also integrated, along with a switched bandwidth fast-lock mode and cycle slip reduction.

Applications for the ADF4350BCPZ include wireless infrastructure (such as W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT), test equipment, wireless LANs, CATV equipment, and general clock generation. The auxiliary RF output can be powered down when not in use, and the device can be muted for isolation requirements.
