The LTC6954IUFF-4 is a 4 output clock driver from Linear Technology which has a variety of applications. It can be used for clocking devices such as ASICs, FPGAs, and general-purpose I/Os. This device is also ideal for converting between high-speed and low-speed clocks and is designed to drive a wide range of logic families. It is highly configurable, with automatic output slew rate control, adjustable drive strength, selectable glitch-free clock switching and jitter attenuation circuitry.

The LTC6954IUFF-4 is a dual-mode, four-output driver. In dual-mode, it can be used to drive two independent clock signals that can be either in the same logic family or in different logic families. In single-mode, it can be configured to drive all four outputs from a single source. It is based on a hybrid architecture that combines the flexibility of Digital Frequency Synthesis (DFS) technology with the power of a high-voltage, low-noise CMOS driver circuitry.

The LTC6954IUFF-4 is designed to work with any standard or proprietary logic family. It is capable of driving both 5V and 3.3V logic and features automatic output slew rate control to minimize overshoot and undershoot. The edge rates can be adjusted from 0 to 15ns and termination adjustments can be made to reduce ringing and ground bounce. It also features jitter attenuation circuitry which can reduce the jitter of a signal by as much as 50%, making it ideal for driving high-speed memories and system clocks.

The LTC6954IUFF-4 also has a wide range of features for sophistication and flexibility. It has selectable glitch-free clock switching and a pin-selectable Drive Strength setting, allowing up to 25mA of output current to drive a wide variety of logic families. It is also programmed using a two-wire serial interface, enabling it to be programmed remotely or in-system. It also has a pin-selectable Auxiliary Input/Output pin, providing access to an external clock source.

The LTC6954IUFF-4 is a versatile clock driver that can be used to drive any standard or proprietary logic family. Its wide range of features make it suitable for a variety of applications, including clocking and clock-frequency generation. Its dual-mode design allows it to drive two distinct clock signals at the same time and its output slew rate control and jitter attenuation circuitry make it ideal for high-speed systems. With its high power drive and pin-selectable features, the LTC6954IUFF-4 is an excellent choice for any clocking application.
