PRELIMINARY

FEMTOCLOCK™ CRYSTAL/LVCMOS-TO-

LVDS/LVCMOS FREQUENCY SYNTHESIZER

ICS8440259-05

ENERAL

ESCRIPTION

The ICS8440259-05 is a 9 output synthesizer

optimized to generate Gigabit and 10 Gigabit Ether-

HiPerClockS™

net clocks and is a member of the HiPerClockS™

family of high performance clock solutions from IDT.

Using a 25MHz, 18pF parallel resonant crystal, the

device will generate 125MHz and 3.90625MHz clocks with mix-

ed LVDS and LVCMOS/LVTTL output levels. The ICS8440259-05

uses IDT’s 3

generations low phase noise VCO technology and

can achieve <1ps typical rms phase jitter, easily meeting Ethernet

jitter requirements. The ICS8440259-05 is packaged in a small,

32-pin VFQFN package that is optimum for applications with

space limitations.

EATURES

•

Five differential LVDS outputs at 125MHz

Three LVCMOS/LVTTL single-ended outputs at 125MHz

One LVCMOS/LVTTL single-ended output at 3.90625MHz

•

Selectable crystal oscillator interface or LVCMOS/LVTTL

single-ended input and PLL bypass from a single select pin

•

VCO range: 490MHz - 680MHz

•

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

(1.875MHz - 20MHz): 0.41ps (typical), LVDS output

•

Full 3.3V supply mode

•

0°C to 70°C ambient operating temperature

•

Available in both standard (RoHS 5) and lead-free (RoHS6)
