IDT5P50911 Datasheet, PDF (1/11 Pages) Integrated Device Technology – 8-pin DFN package

SPREAD SPECTRUM CLOCK SYNTHESIZER
DATASHEET
IDT5P50911/2/3/4
Description
The IDT5P50911/2/3/4 is a family of 1.8V/2.5V/3.3V low
power, spread spectrum clock generators capable of
reducing EMI radiation from an input clock. Spread
spectrum technique is capable of reducing the harmonic
frequency amplitude peaks by several dB.
