DATA SHEET  
ICS84314  
350MHZ, CRYSTAL-TO-3.3V/2.5V LVPECL FREQUENCY  
SYNTHESIZER W/FANOUT BUFFER  
FEATURES  
GENERAL DESCRIPTION  
Fully integrated PLL  
The ICS84314 is a general purpose quad output  
ICS  
frequency synthesizer and a member of the  
4 differential 3.3V or 2.5V LVPECL outputs  
HiPerClockS™  
HiPerClockS™ family of High Performance Clock  
Solutions from ICS. When the device uses par- Selectable crystal oscillator interface  
allel loading, the M bits are programmable and  
the output divider is hard-wired for divide by 2 thus providing  
a frequency range of 125MHz to 350MHz. In serial program-  
ming mode, the M bits are programmable and the output di-  
vider can be set for either divide by 2 or divide by 4, providing  
a frequency range of 62.5MHz to 350MHz. The low cycle-  
cycle jitter and broad frequency range of the ICS84314 make  
it an ideal clock generator for a variety of demanding applica-  
tions which require high performance.  
or LVCMOSTEST_CLK input  
Output frequency range: 62.5MHz to 350MHz  
VCO range: 250MHz to 700MHz  
Parallel interface for programming counter  
and output dividers during power-up  
Serial 3 wire interface  
Cycle-to-cycle jitter: 23ps (typical)  
Output skew: 16ps (typical)  
Output duty cycle: 49% < odc < 51%, fout 125MHz
