FEMTOCLOCK™ CRYSTAL-TO-

3.3V LVPECL FREQUENCY SYNTHESIZER

ICS843204I

GENERAL DESCRIPTION

FEATURES

The ICS843204I is a 4 output LVPECL Synthesizer

• Four 3.3V LVPECL outputs

ICS

HiPerClockS™

optimized to generate Gigabit Ethernet and SONET

reference clock frequencies and is a member of the

HiPerClocks^TMfamily of high performance clock

solutions from IDT. Using a 19.44MHz and 25MHz,

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• Supports the following output frequencies: 155.52MHz

and 156.25MHz

18pF parallel resonant crystal, 155.52MHz and 156.25MHz

frequencies can be generated. The ICS843204I uses IDT’s

FemtoClock^TMlow phase noise VCO technology and can achieve

1ps or lower typical RMS phase jitter. The ICS843204I is pack-

aged in a 48-pin TSSOP package.

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal

(12kHz - 20MHz): 0.98ps (typical)

• RMS phase jitter @ 156.25MHz, using a 19.44MHz crystal

(1.875MHz - 20MHz): 0.52ps (typical)

• Full 3.3V supply mode

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

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