PRELIMINARY  
FEMTOCLOCK™ CRYSTAL/LVCMOS-TO-  
LVDS/LVCMOS FREQUENCY SYNTHESIZER  
ICS8440259-45  
GENERAL DESCRIPTION  
ICS  
FEATURES  
One differential LVDS output at 156.25MHz or 125MHz  
The ICS8440259-45 is a 9 output synthesizer  
optimized to generate Gigabit and 10 Gigabit  
Ethernet clocks and is member of the  
Four differential LVDS outputs at 125MHz  
Three LVCMOS/LVTTL single-ended outputs at 125MHz  
One LVCMOS/LVTTL single-ended output at 3.90625MHz  
HiPerClockS™  
a
HiPerClockS™family of high performance clock  
solutions from IDT. Using a 25MHz, 18pF parallel  
Selectable crystal oscillator interface or LVCMOS/LVTTL  
single-ended input and PLL bypass from a single select pin  
resonant crystal, the device will generate both 156.25MHz,  
125MHz and 3.90625MHz clocks with mixed LVDS and  
LVCMOS/LVTTL output levels. The ICS8440259-45 uses IDT’s  
3rd generation low phase noise VCO technology and can  
achieve <1ps typical rms phase jitter, easily meeting Ethernet  
jitter requirements. The ICS8440259-45 is packaged in a small,  
5mm x 5mm VFQFN package that is optimum for applications  
with space limitations.  
VCO range: 490MHz - 680MHz  
RMS phase jitter @ 125MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.41ps (typical), LVDS output  
RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.41ps (typical), LVDS output  
LVDS supply voltage modes: full 3.3V and full 2.5V  
LVCMOS supply voltage modes:  
Core/Output Core/Output  
3.3V/3.3V 3.3V/2.5V  
Core/Output  
2.5V/2.5V  
0°C to 70°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS6)  
packages
