The IDT5V551DCI is a clock buffer with an integrated differential PECL (positive emitter-coupled logic) driver. This device is often used to distribute clock signals where high-speed and fan-out are of primary importance.

The IDT5V551DCI is a versatile clock output device, featuring an adjustable-delay (3 - 20ns), single-ended, and non-inverting differential PECL outputs. This device provides one differential PECL output as well as two differential outputs, so it can be used for both general-purpose clock distribution applications and for driving complex source-synchronous interfaces in telecommunications and data communication applications.

The IDT5V551DCI operates from a 1.8 - 5.5 V DC power supply and has an input frequency range of up to 2.2 – 3.6 GHz. It provides up to 1.8GHz of output frequency and is designed for data rates up to 3.6 Gigabits/s. The device is also designed for low-skew applications with very low jitter of less than 5ps over a wide frequency range.

In terms of its working principle, the IDT5V551DCI utilizes a differential PECL driver output stage. This driver stage accepts a single-ended input signal and converts it into a differential output signal. It then drives the differential outputs to either a logic high or low level. The output stage is designed to have very low power consumption, with a total output power of just 0.6W. The device also features an adjustable delay line, allowing the user to customize the output timing parameters to their specific application.

Overall, the IDT5V551DCI is a versatile, low-power differential PECL buffer with adjustable delay for distributing fast clocks. It can be used in a variety of applications, such as clock distribution for consumer electronics, telecommunications, and high-speed data communication.
