ADF4159WCCPZ

ADF4159WCCPZ is Analog Devices’ wideband fractional-N frequency synthesizer (PLL). It generates RF outputs by synthesizing a local oscillator from a stable reference clock, enabling fine frequency steps and fast lock in RF front-ends.
Key points:
- Wideband fractional-N PLL with programmable dividers and modulus for precise frequency steps.
- SPI/serial interface for programming N, modulus, reference divider, power modes, and lock-detect settings.
- Requires an external reference oscillator and loop filter; suitable for low-noise RF synthesis.
- Used in wireless transceivers, radar, test equipment, and agile RF systems.
- WCCPZ denotes its specific package/temperature grade from Analog Devices.
In short, it’s a flexible, high-performance RF synthesizer ideal for agile, high-frequency applications where precise, programmable frequency generation is needed.

Here are the typical features of the ADF4159WCCPZ (Analog Devices fractional-N PLL synthesizer):
- Fractional-N frequency synthesizer with programmable N and FRAC for fine frequency steps.
- Dual-modulus prescaler for wide RF range and flexibility.
- SPI-compatible (and 3-wire) control interface for register programming.
- Wide reference input options (external reference with adjustable divider, low-jitter references).
- Programmable output frequency across a broad RF range (up to several GHz depending on config and external components).
- Programmable modulus and fraction control for high-resolution tuning and reduced spurs.
- Lock detect and power-down modes for system integration and power management.
- Low phase-noise performance suitable for RF transceivers and communications.
- Optional features for fast lock, calibration, and test modes.
- RoHS-compliant package: WCCPZ version in a suitable LFCSP/lead-frame package (specific per order).
Note: exact RF max, reference ranges, and some capabilities depend on the specific configuration and external components used.

The ADF4159WCCPZ comes in a 16‑lead LFCSP package (lead-frame, 4x4 mm), RoHS-compliant.
