General Description

The IDT8T79S828-08I 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

IDT8T79S828-08I 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.
