FEMTOCLOCKS™ CRYSTAL-TO-HSTL CLOCK GENERATOR

ICS842023

General Description

Features

The ICS842023 is an Ethernet Clock Generator and

• One differential HSTL output pair

a member of the HiPerClocks^TMfamily of high

performance devices from IDT. For Ethernet

applications, a 25MHz crystal is used to generate

250MHz. The ICS842023 uses IDT 3^rdgeneration

• Crystal oscillator interface, 18pF parallel resonant crystal

HiPerClockS™

(24.5MHz – 34MHz)

• Output frequency range: 245MHz – 340MHz

• VCO range: 490MHz – 680MHz

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

phase jitter, easily meeting Ethernet jitter requirements. The

ICS842023 is packaged in a small 8-pin TSSOP, making it ideal for

use in systems with limited board space.

• RMS phase jitter at: 250MHz, using a 25MHz crystal

(1.875MHz – 20MHz): 0.23ps (typical)

• Full 3.3V or 2.5V output supply modes

• 0°C to 70°C ambient operating temperature

• Available in both standard (RoHS 5) and lead-free (RoHS 6)
