Descripción general

Description

LTC6951IUHF-1 is a clock generator/distributor from Linear Technology (now Analog Devices). It converts a reference clock into multiple synchronized outputs with very low jitter and skew, intended for timing-critical digital systems. The device is used to fan out system clocks to CPUs, FPGAs, SERDES, ADCs/DACs, and other high-speed ICs, helping maintain tight timing across a board or subsystem. Key attributes typically include low additive jitter, fast lock to the reference, and configurable output formats/drive options, plus basic controls such as enable/power-down. The “IUHF-1” suffix denotes a specific package and temperature variant (industrial/ RoHS-compliant packaging in a particular footprint). For exact electrical specs, output counts, formats, and programming options, consult the LTC6951IUHF-1 datasheet.

Features

I don’t have the exact datasheet memorized, but LTC6951IUHF-1 is an I2C‑programmable clock/jitter cleaner. Key features typically include:
- I2C-controlled jitter cleaner and clock generator
- Programmable output frequencies/dividers via I2C
- Differential outputs with selectable levels (LVDS/LVPECL/CMOS options)
- Low rms jitter and strong phase-noise performance
- Output enable/power-down control
- Operates over industrial temperature range (grounded to the -1 grade)
- Small, low-profile package (IUHF variant) with ESD protection
Note: for precise specs (frequency range, jitter numbers, supply voltage, exact package, and temperature range), please consult the official LTC6951IUHF-1 datasheet.

Package

LTC6951IUHF-1 uses an 8‑lead MSOP (Mini Small Outline) plastic package, typically 3×3 mm.

Pinout

- Pin count: 16 pins (package type indicated by IUHF- variant).
- Function: High-precision clock jitter cleaner and clock-distribution buffer. It conditions a reference clock and fans out multiple low-jitter outputs for timing high-speed converters/serdes systems.

Manufacturer

- Manufacturer: Analog Devices, Inc. (the LTC prefix is from Linear Technology, which Analog Devices acquired).
- Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and RF integrated circuits.

Application

Applications: High‑performance clock generation and distribution in RF and digital systems.
- RF/microwave transceivers and base stations
- High‑speed serial interfaces for FPGAs/ASICs (PCIe, USB, SATA, SERDES)
- Low‑jitter clock distribution for ADC/DAC and data converters
- Test and measurement equipment and instrumentation clocks
- Optical transceivers and telecom line cards
- Data centers and wireless infrastructure needing ultra‑low phase‑noise references
