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 thru ÷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.
