ADF4350BCPZ

The ADF4350BCPZ is a wideband PLL frequency synthesizer with an integrated voltage-controlled oscillator (VCO) from Analog Devices. It supports both fractional-N and integer-N synthesis modes, covering an output frequency range from 137.5 MHz to 4.4 GHz. The device accepts CMOS or TTL inputs and provides a single clock output. It includes a programmable divide-by-1, 2, 4, 8, or 16 output divider, allowing flexible frequency generation. The typical jitter performance is less than 0.4 ps rms, and the logic interface is compatible with 1.8V levels.

The synthesizer operates from a 3.0V to 3.6V supply and is specified over the industrial temperature range of -40°C to +85°C. It features a 1:2 input-to-output ratio and does not provide differential inputs or outputs. The integrated VCO covers 2200 MHz to 4400 MHz, and the output divider extends the range down to 137.5 MHz. The device includes a 3-wire serial interface for programming and provides analog and digital lock detect signals.

The ADF4350BCPZ is housed in a 32-lead LFCSP (leadframe chip scale package) with an exposed pad, measuring 5 mm x 5 mm. It is designed for surface mount assembly and is suitable for applications requiring low phase noise, low jitter clock generation, such as wireless infrastructure, test equipment, and CATV systems.
