FemtoClock® NG Crystal-to-3.3V LVPECL  
Clock Generator  
843001  
DATA SHEET  
GENERAL DESCRIPTION  
FEATURES  
The 843001 is a Fibre Channel Clock Generator and a member  
of the family of high performance devices from IDT. The 843001  
uses either a 26.5625MHz or a 23.4375 crystal to synthesize  
106.25MHz, 187.5MHz or 212.5MHz, using the FREQ_SEL pin.  
The 843001 has excellent <1ps phase jitter performance, over the  
637kHz – 10MHz integration range. The 843001 is packaged in a  
small 8-pin TSSOP, making it ideal for use in systems with limited  
board space.  
One differential 3.3V LVPECL output  
Crystal oscillator interface designed for 23.4375MHz or  
26.5625MHz, 18pF parallel resonant crystal  
Selectable 106.25MHz, 187.5MHz or 212.5MHz
