FEMTOCLOCK™ CRYSTAL-TO-

ICS843SDN

3.3V LVPECL CLOCK GENERATOR

General Description

Features

The ICS843SDN is a Gigabit Ethernet Clock

• One differential 3.3V LVPECL output

Generator and a member of the HiPerClocks^TM

family of high performance devices from IDT. The

ICS843SDN uses a 24MHz crystal to synthesize

120MHz. The ICS843SDN uses IDT’s 3^rdgeneration

• Crystal oscillator interface designed for 23.2MHz – 30MHz,

HiPerClockS™

18pF parallel resonant crystal

• Output frequency range: 116MHz – 150MHz

• VCO range: 580MHz – 750MHz

low phase noise VCO technology, and can achieve <1ps rms

phase jitter performance over the 12kHz – 20MHz integration

range. The ICS843SDN is packaged in a small 8-pin TSSOP,

making it ideal for use in systems with limited board space.

• Output duty cycle range: 47% – 53%

• RMS phase jitter @ 120MHz, using a 24MHz crystal

(12kHz – 20MHz): 0.81ps (typical)

• Full 3.3V supply mode

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request

• Available in lead-free (RoHS 6) package
