The IDT49FCT805SO8 is an advanced, high-performance clock buffer designed to provide reliable and accurate operation in an assortment of data and communications systems, including those used in applications such as clock distribution and rate-changing. This device has integrated voltage-controlled oscillators (VCOs), as well as numerous customizable input and output configurations. In addition, the IDT49FCT805SO8 is designed to provide a low power requirement, making it an ideal choice for battery-powered or space-limited designs.

The IDT49FCT805SO8 belongs to a category of clock/timing devices known as clock buffers, drivers, and regenerators. This type of device is responsible for, among other things, providing clock signal synchronization, duplication, distribution, buffering, and signal transmission. Clock signal regeneration is an integral part of clock buffer usage, as the device can eventually wear out from too many input/output cycles. The purpose of these devices is to provide an enhanced signal, which is sometimes referred to as a “clean” signal, which is free of any external noise or crosstalk. This cleans signal can then be used by other system components to ensure Synchronous or distributed timing.

The IDT49FCT805SO8 has four independent output buffers and two independent building-in VCOs. With the VCOs, the device can provide a wide range of output frequencies from 3.2 MHz to 125 MHz and a wide range of input frequencies from 1.6 MHz to 650 MHz, allowing it to be used in a range of data-communications systems such as USB, Firewire, Gigabit and 10 Gigabit Ethernet, and FDDI. The device can be driven by either a push-pull or a differential clock, which allows designers to easily scale the device up or down depending on their needs.

The IDT49FCT805SO8 relies on phase-locked-loop (PLL) technology to provide superior phase and frequency accuracy. A PLL is a closed loop control system that automatically compares the frequency and phase of one signal to another, and then adjusts its output accordingly. In the case of the IDT49FCT805SO8, the reference source (usually an external clock source) is fed into the VCOs, which then shifts the input frequency to the desired output frequency. The device then synchronizes the frequencies, ensuring that the output clock is in perfect sync with the input clock.

The IDT49FCT805SO8 is a great choice for anybody looking for a reliable, robust, and low power clock/timing device for their system. Its wide range of input and output frequencies and the ability to drive both push-pull and differential inputs make it the perfect choice for a range of data-communications and clock distribution applications. It definitely represents the cutting edge in clock buffer technology, and is sure to be found in more than a few designs over the coming years.
