Overview

Description

ADF4350BCPZ-RL is Analog Devices’ wideband PLL frequency synthesizer with an integrated VCO and RF output buffer. It generates precise RF frequencies by digitally dividing a reference clock (via N, MOD/FRAC) in a fractional- or integer-N loop. Typical RF output range is about 35 MHz up to 4.4 GHz, with a reference input up to tens of MHz (often up to 50 MHz depending on variant). Programming is done via a serial SPI interface (registers control N, modulus, R divider, output dividers, power, and lock options). It includes a phase detector, charge pump, lock detect, and an internal loop-filter-friendly architecture, requiring an external loop filter and RF matching network. Applications: wireless transceivers, RF test equipment, SDRs, and other systems needing flexible, high-stability frequency synthesis. The -RL suffix indicates tape-and-reel packaging; BCPZ is the package code for the RoHS-compliant variant.

Features

Key features of ADF4350BCPZ-RL:
- Fully integrated wideband PLL synthesizer with internal VCO
- RF output up to 4.4 GHz (wideband coverage for wireless/radio applications)
- Fractional-N and integer-N operation with programmable modulus (MOD) for fine frequency steps
- Built-in phase-frequency detector, charge pump, and lock detect
- SPI digital interface with programmable N, MOD, R-counter/dividers, and RF divider settings
- Flexible reference input with programmable reference divider (supports external reference clock)
- External loop filter required; enables design of desired loop dynamics
- Low phase noise and spurious performance suitable for RF front-ends
- RoHS-compliant 28-pin LFCSP (BCPZ) packaging, tape-and-reel RL variant
Applications: wireless transceivers, point-to-point links, RF front-ends, instrumentation, and other wideband frequency synthesis needs.

Package

Package type: 28‑lead LFCSP (lead-frame chip-scale package). The “-RL” means tape/reel shipping.

Pinout

- Pin count: 28 pins (LQFP-28, RoHS package; BCPZ; -RL denotes tape-and-reel).
- Function: ADF4350BCPZ-RL is a wideband fractional-N PLL synthesizer with integrated VCO. It uses an SPI-compatible interface to program the frequency (reference divider, feedback/dividers, modulus), provides an RF output (RFOUT) and reference input (REFIN), includes a lock-detect output, and has standard power/ground pins (DVDD, AVDD, GND).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for communications, instrumentation, and related applications.
