LTC6951IUHF-1#PBF

Clock Generators, PLLs, Frequency Synthesizers Overview

The LTC6951IUHF-1#PBF is a multi-output integer-N phase-locked loop (PLL) clock synthesizer manufactured by Analog Devices, formerly Linear Technology. It integrates a voltage-controlled oscillator (VCO) and supports five independent outputs with frequencies ranging from 1.95 MHz to 2.5 GHz. The device operates on a single 3.3V supply and features low jitter performance suitable for high-speed data converters. Key electrical parameters include an integrated VCO, integer-N synthesis architecture, and support for external reference inputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The LTC6951 belongs to the LTC695x family of clock synthesizers designed for applications requiring multiple synchronized clocks with minimal jitter. The IUHF-1 suffix indicates an industrial temperature range (-40°C to +85°C) and a specific package configuration (LFCSP). This component is widely used in systems where clean clock signals are critical for signal integrity in high-frequency digital circuits.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public documentation lists the HMC7043 as a potential successor or alternative within the Analog Devices portfolio for similar multi-output clocking requirements. Designers should verify pin compatibility and feature sets when considering substitutes.
