Overview
Description
The 8T79S818I-08 is a high-performance, 1-to-8, differential input to universal output clock divider and fanout buffer. The device is designed for frequency division and signal fanout of high-frequency clock signals in applications requiring four different output frequencies generated simultaneously. Each bank of two outputs has a selectable divider value of ÷1 through ÷6 and ÷8. The 8T79S818I-08 is optimized for 3.3V and 2.5V supply voltages and a temperature range of -40 °C to 85 °C. The device is packaged in a space-saving 32-lead VFQFN package.

Description
IDT's innovative support tool, Timing Commander™, expedites development cycles by empowering customers to program sophisticated timing devices with an intuitive and flexible Graphical User Interface. IDT's Timing Commander is a Windows™-based platform designed to serve user-friendly configuration interfaces, known as personalities, for various IDT products and product families. With a few simple clicks, the user is presented with a comprehensive, interactive block diagram offering the ability to modify desired input values, output values, and other configuration settings. The software automatically makes calculations, reports status monitors, and prepares register settings without the need to reference a datasheet. The tool also automatically loads the configuration settings over USB to an IDT evaluation board for immediate application in the circuit. Once the device has been configured and tuned for optimal system performance, the configuration file can be saved for factory-level programming before shipment.

Narrator: In a data driven world, timing is everything. That's why more and more system design engineers are using products from the world leader in silicon timing, IDT. IDT has earned its reputation for excellence by providing a wide range of leading technologies for wireless and wired communications infrastructure, high performance computing, and advanced power management.
And with a product portfolio 10 times greater than the competition, IDT is uniquely qualified to be your one-stop-shop for timing solutions. IDT's innovative Windows-based software platform, Timing Commander, makes it easy to configure, program, and monitor all your sophisticated timing devices.
Steven: What's great about IDT's Timing Commander is that it helps you avoid tedious manageable configurations so you can focus on other areas of your design.
Narrator: IDT's Timing Commander serves up intuitive configuration interfaces or personalities for all of IDT's programmable timing products. With a few simple clicks, you can generate a comprehensive, interactive block diagram and modified desired input values, output values, and other configuration settings. The software also writes your settings over USB to an IDT evaluation board for immediate application in the circuit. It really is as easy as one, two, three.
Steven: The Timing Commander software automatically makes calculations, monitors status, and prepares register settings so you don't have to reference a data sheet. Built-in documentation is readily available. Just hover over a setting, and real time validation ensures that the configuration complies with data sheet specifications. Whether you're a first time user or an experienced engineer, Timing Commander offers you the right amount of control.
Narrator: To help you program complex devices more intuitively, Timing Commander's advanced features include the ability to create phase noise estimates, generate the schematic symbol and termination circuit and determine the optimal balance between performance and power consumption.
Steven: Once your devices are configured and tuned for optimal system performance, you can save the configuration files for factory-level programming prior to shipment.
Narrator: Timing Commander is just one example of the innovative timing solutions IDT delivers.
Peter: From simple fanout buffers and multiplexers to fully featured products like universal frequency translators, network synchronization devices, and VersaClock families, IDT has a wide range of products optimized for specific applications. You can also count on IDT for the lowest jitter and lowest power features to help you build the world class products your customers demand.
Narrator: It's time to put IDT timing solutions to work for your business, and with the power of Timing Commander software, it's easier than ever. To learn more, visit IDT online or give us a call today.
