IDT5P50911

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.
