FEMTOCLOCK™ CRYSTAL-TO-LVCMOS/LVTTL

CLOCK GENERATOR

ICS840021

General Description

The ICS840021 is a Gigabit Ethernet Clock

Generator and a member of the HiPerClocks

HiPerClockS™

family of high performance devices from IDT. The

ICS840021 uses a 25MHz crystal to synthesize

125MHz. The ICS840021 has excellent phase jitter

performance, over the 1.875MHz – 20MHz integration range. The

ICS840021 is packaged in a small 8-pin TSSOP, making it ideal for

use in systems with limited board space.

Features

•

One LVCMOS/LVTTL output, 7Ω output impedance

Crystal oscillator interface designed for 25MHz,

18pF parallel resonant crystal

Output frequency: 125MHz

VCO range: 560MHz to 680MHz

RMS phase jitter @ 125MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.34ps (typical) 3.3V

RMS phase noise at 125MHz (typical)

Phase noise:

Offset

Noise Power

100Hz ................-96.9 dBc/Hz

1kHz ..............-122.2 dBc/Hz

10kHz ..............-131.1 dBc/Hz

100Hz ..............-129.5 dBc/Hz
