Overview

Description

LTC6953IUKG#PBF is a Linear Technology (now Analog Devices) high-performance clock generator/jitter cleaner. It accepts a reference clock and provides one or more low-jitter, phase-aligned output clocks for high-speed digital systems. The device includes an internal PLL with programmable multiplication/division and supports versatile output formats (LVDS/LVPECL/CMOS), making it suitable for clock distribution to FPGAs, SerDes, and RF front-ends with tight jitter and skew requirements. The suffix IUKG indicates the specific package/temperature option, and #PBF denotes Pb-free packaging. Typical benefits: low additive jitter, programmable output frequencies, and robust jitter cleaning under varying loads. Common applications include PCIe, Ethernet, memory interfaces, and other timing networks. For exact electrical specs (input range, supply, output levels, jitter figures, and package details), consult the official LTC6953 datasheet and packaging documentation.

Package

Pb-free 28-lead Plastic Quad Flat Package (LQFP).

Pinout

Pin count: 28 pins.
Function: LTC6953IUKG#PBF is a high‑speed clock generator/PLL (low‑jitter clock synthesizer) with multiple outputs for clock distribution. It takes a reference clock and provides programmable multiplication/division to generate low‑noise output clocks for system components.

Manufacturer

Manufacturer: Analog Devices, Inc. (AD). The LTC6953 was originally from Linear Technology and is now produced by Analog Devices after their 2017 acquisition.
Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.

Application

Applications of LTC6953IUKG#PBF:
- High-speed data communications and backplanes
- Clock distribution and jitter cleaning for FPGAs/ASICs/SERDES (PCIe, SATA, Gigabit Ethernet)
- Telecom and datacom line cards
- RF/microwave test equipment
- Instrumentation and embedded systems needing multiple low-jitter, synchronized reference clocks
(Note: Industrial temperature variant suitable for -40°C to 85°C environments.)
