FemtoClock^®NG Crystal-to-LVCMOS/

LVTTL Clock Synthesizer

ICS840N011I

DATASHEET

General Description

Features

The ICS840N011I is an LVCMOS/LVTTL clock synthesizer designed

for Fibre Channel applications. The device generates a 106.25MHz

clock signal from a 26.5625MHz crystal or a 100MHz clock signal

from a 25MHz crystal with excellent phase jitter performance. The

device uses IDT’s fourth generation FemtoClock^®NG technology for

an optimum of high clock frequency, low phase noise performance

and low power consumption and high power supply noise

rejection.The device supports 2.5V or 3.3V voltage supply and is

packaged in a small, lead-free (RoHS 6) 8-lead TSSOP package.

The extended temperature range supports wireless infrastructure,

telecommunication and networking end equipment requirements.

• Fourth generation FemtoClock^®NG technology

• 106.25MHz output clock synthesized from a 26.5625MHz

fundamental mode crystal

• One 2.5V or 3.3V LVCMOS/LVTTL clock output

• Crystal interface designed for a 12pF parallel resonant crystal

• RMS phase jitter @ 100MHz, using a 25MHz crystal

(637kHz - 10MHz): 0.185ps (maximum)

• LVCMOS/LVTTL interface level for the output enable input

• Full 2.5V or 3.3V supply voltage

• Lead-free (RoHS 6) packaging

• -40°C to 85°C ambient operating temperature
