説明

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.
