Systems, Incꢀ  
CRYSTAL-TO-LVDS  
INTEGRATED FREQUENCY SYNTHESIZER/FANOUT BUFFER  
GENERAL DESCRIPTION  
FEATURES  
The ICS84427 is a Crystal-to-LVDS Frequency Syn- 6 LVDS outputs  
thesizer/Fanout Buffer and a member of the  
HiPerClockS™ family of High Performance Clock  
Solutions from ICS. The output frequency can be pro-  
grammed using the frequency select pins. The low  
Crystal oscillator interface  
HiPerClockS™  
Output frequency range: 77.76MHz to 625MHz  
Crystal input frequency: 19.44MHz, 25MHz or 25.5MHz  
Cycle-to-cycle jitter: 25ps (typical)  
phase noise characteristics of the ICS84427 make it an ideal clock  
source for 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, OC3  
and OC12 applications.  
RMS phase jitter at 155.52MHz, using a 19.44MHz crystal  
(12KHz to 20MHz): TBD
