概述

Description

LTC6957IDD-3#TRPBF is an industrial-temperature clocking IC from Analog Devices (Linear Technology lineage). It belongs to the LTC6957 family and is used to condition and distribute clean, low-jitter clock signals for high-speed digital systems (FPGA/ASIC SERDES, memory interfaces, etc.). The device typically integrates a PLL-based clock generator with programmable features to produce stable output clocks in multiple formats, offering low additive jitter and controlled skew among outputs.
- -IDD indicates Industrial temperature range (-40°C to +85°C).
- -3 denotes a specific output/voltage option within the family.
- #TRPBF indicates Tape‑and‑Reel packaging and Pb-free, RoHS-compliant material.
For exact electrical specs, output formats, programmable options, and pinout, consult the LTC6957 data sheet and the Analog Devices product page.

Package

32‑lead Plastic LQFP (low-profile quad flat package), Pb‑free RoHS, supplied in tape‑and‑reel (TRPBF).

Pinout

Pin count: 10 pins (10‑lead DFN package, part suffix IDD).
Function: programmable, low‑jitter clock fanout/divider IC — accepts a single‑ended or differential input and provides multiple low‑jitter clock outputs with selectable divide ratios, output enable/reset control and multi‑standard output levels (CMOS/LVDS/LVPECL depending on configuration). Suitable for clock distribution and timing applications.

Manufacturer

Manufacturer: Analog Devices, Inc. (the LTC prefix denotes Linear Technology, which was acquired by Analog Devices in 2017).
What kind of company: Analog Devices is a multinational semiconductor company that designs and manufactures high-performance analog, mixed-signal, and RF integrated circuits (including clock/timing, power management, data converters, amplifiers and signal-chain products) for industrial, automotive, communications, consumer and instrumentation markets.

Application

Applications include:
- Clock distribution for FPGAs, ASICs, and DSPs
- High-speed SERDES reference clocks (PCIe, SATA, USB, Ethernet)
- Multi-domain timing in data communications, telecoms and backplanes
- Instrumentation and test equipment requiring low-noise references
- Data-center and telecom timing architectures
- Microprocessor/memory timing networks with multiple clock domains
