PRELIMINARY  
FEMTOCLOCKS™ CRYSTAL-TO-LVDS  
FREQUENCY SYNTHESIZER  
ICS844001-21  
GENERAL DESCRIPTION  
FEATURES  
The ICS844001-21 is a a highly versatile, low  
• One differential LVDS output pair and  
one LVCMOS reference output  
ICS  
phase noise LVDS Synthesizer which can generate  
low jitter reference clocks for a variety of  
communications applications and is a member of  
the HiPerClocksTM family of high performance clock  
HiPerClockS™  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
solutions from IDT. The dual crystal interface allows the  
synthesizer to support up to two communications standards in  
a given application (i.e. 1GB Ethernet with a 25MHz crystal  
and 1Gb Fibre Channel using a 25.5625MHz crystal). The rms  
phase jitter performance is typically less than 1ps, thus making  
the device acceptable for use in demanding applications such  
as OC48 SONET and 10Gb Ethernet. The ICS844001-21 is  
packaged in a small 24-pin TSSOP package.  
• VCO range: 560MHz - 700MHz  
• Supports the following applications:  
SONET, Ethernet, Fibre Channel, Serial ATA, and HDTV  
• RMS phase jitter @ 622.08MHz (12kHz - 20MHz):  
0.92ps (typical)  
• Full 3.3V supply mode  
• 0°C to 70°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
