概要

Description

ADF4155BCPZ-RL7 is Analog Devices’ wideband fractional-N PLL frequency synthesizer. It generates tunable RF outputs by locking an external VCO/RF network to a reference clock via a programmable feedback divider (integer N plus fractional FRAC/MOD). A low-noise phase detector and prescaler enable narrow linewidth and low spurs. Programming is via a serial SPI interface to set N, FRAC/MOD, reference divider, and other options; features include fractional-N dithering, lock detect, and power-down. It supports various reference frequencies and modes (fractional-N or integer-N) to balance resolution and spur performance. Typical applications: wireless transceivers, microwave links, radar front-ends, and test equipment needing a tunable LO. The -RL7 suffix denotes RoHS-compliant tape-and-reel packaging; CPZ is the package code for the 28-pin LFCSP. For exact electrical characteristics, pinout, and programming sequences, refer to the datasheet and supporting tools.

Features

Key features of ADF4155BCPZ-RL7 (concise):
- Wideband fractional-N PLL synthesizer with an integrated VCO
- RF output range over a broad GHz band with low phase noise and reduced spurs
- On-chip prescaler and programmable modulus for fractional division
- SPI-compatible serial interface for full programming (N value, fractional part, phase, CP current, lock detect, etc.)
- Programmable reference input and reference divider options for flexible reference timing
- Adjustable output/divider configuration and VCO selection
- Programmable charge-pump current, power-down mode, and fast lock time
- Low jitter performance and robust spur suppression via fractional-N architecture
- Industrial-temperature range support
- 28-pin LFCSP, lead-free (RL7) package; RoHS-compliant
Note: exact figures (frequencies, dividers, currents, etc.) are device-specific. Please refer to the datasheet for precise specifications.

Package

It's an LFCSP (20-lead) package, 5x5 mm, RoHS-compliant; -RL7 indicates tape-and-reel packaging.

Pinout
