ICS843020-01

FEMTOCLOCKS™ 680MHZ, CRYSTAL-TO-

3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

The ICS843020-01 is a general purpose, dual out-

put Crystal-to-3.3V Differential LVPECL High Fre-

quency Synthesizer and a member of the

FemtoClocks™ family of High Performance Clock

Solutions from ICS. The ICS843020-01 is based

on ICS’ 3rd generation VCO technology and is capable of sub-

1ps RMS Phase Jitter performance, making it ideal for use in

10 Gigabit Ethernet, 10 Gigabit Fibre Channel, SONET and

Serial ATA applications.

The ICS843020-01 is a highly flexible programmable synthe-

sizer capable of generating output frequencies over a range of

70MHz to 680MHz. The output frequency can be programmed

in small step sizes as low as 250

kHz when using a 16MHz

crystal,

÷8 input divider, and output divider = ÷8.
