DATASHEET SPREAD SPECTRUM CLOCK SYNTHESIZER IDT5P50911/2/3/4 Description Features The IDT5P50911/2/3/4 is a family of 1.8V/2.5V/3.3V low 8-pin DFN package (2x2mm) power, spread spectrum clock generators capable of 8-pin MSOP package (3x4.9mm) reducing EMI radiation from an input clock. Spread Provides a spread spectrum output clock spectrum technique is capable of reducing the harmonic Crystal input frequency range of 10 to 30 MHz frequency amplitude peaks by several dB. Output frequency range of 10 to 120 MHz Ordering Information Center and down spread Peak reduction by 8 dB to 16 dB typical on 3rd through Output Frequency 19th odd harmonics 5 to 15 MHz - 5P50911NBGI/5P50911DVGI 10 to 30 MHz - 5P50912NBGI/5P50912DVGI Low EMI feature can be disabled 20 to 60 MHz - 5P50913NBGI/5P50913DVGI Operating voltage of 1.8 V, 2.5 or 3.3V 40 to 120 MHz - 5P50914NBGI/5P50914DVGI RoHS 6 compliant package Spread Modulation Frequency Table Part Output Input Modulation Input Modulation Modulation Number Multiply (MHz) (kHz) (MHz) (kHz) Frequency (kHz) 5P50911 1/2x Input frequency 10 27 30 81 *27/10000 5P50912 1x 5P50913 2x 5P50914 4x Block Diagram VDD OE S1:S0 PLL Clock Synthesizer with X1 CLKOUT Spread Spectrum Crystal Circuitry Oscillator X2 Optional tuning GND crystal capacitors IDT SPREAD SPECTRUM CLOCK SYNTHESIZER 1 IDT5P50911/2/3/4 REV D 070214IDT5P50911/2/3/4 SPREAD SPECTRUM CLOCK SYNTHESIZER CLOCKSYNTHESIZER Pin Assignment 1 X1/ICLK 8 X2 VDD GND OE CLKOUT 4 5 S0 S1 8-pin DFN 8 -pin MSOP Spread Direction and Percentage Select Table S1 S0 Spread Spread Direction Percentage 00 OFF -- 0 1 Center 0.5 1 0 Center 1.5 11 Down -0.5 Pin Description Pin Pin Pin Type Pin Description Number Name 1 X1 XI Crystal input.
