GENERAL DESCRIPTION  
FEATURES  
The ICS8431-01 is a general purpose clock • Fully integrated PLL  
frequency synthesizer for IA64/32 applications  
• Differential 3.3V LVPECLoutput  
HiPerClockS™  
and a member of the HiPerClockS™ family of High  
Performance Clock Solutions from ICS. The  
ICS8431-01 consists of one independent low  
• Crystal oscillator interface  
• Output frequency: 200MHz  
• 48% to 52% duty cycle  
bandwidth PLL timing channel. A 16.666MHz crystal is used  
as the input to the on-chip oscillator. The M divide is config-  
ured to produce a fixed output frequency of 200MHz.  
• Spread Spectrum Clocking (SSC) fixed at 1/2% modulation  
for environments requiring ultra low EMI. Typical10dB EMI  
reduction can be achieved with spread spectrum modulation  
Programmable features of the ICS8431-01 support four  
operational modes. The four modes are spread spectrum  
clocking (SSC), non-spread spectrum clocking and two test  
modes which are controlled by the SSC_CTL[1:0] pins. Un-  
like other synthesizers, the ICS8431-01 can immediately  
change spread-spectrum operation without having to reset  
the device.  
• PLLbypass modes supporting in-circuit testing and on-chip  
functional block characterization  
• Cycle-to-cycle jitter: 30ps (maximum)  
• 3.3V supply voltage  
In SSC mode, the output clock is modulated in order to  
achieve a reduction in EMI. In one of the PLL bypass test  
modes, the PLL is disconnected as the source to the  
differential output allowing an external source to be  
connnected to the TEST_I/O pin. This is useful for in-  
circuit testing and allows the differential output to be driven  
at a lower frequency throughout the system clock tree. In the  
other PLL bypass mode, the oscillator divider is used as the  
source to both the M divide and the Fout divide by 2. This is  
useful for characterizing the oscillator and internal dividers.  
• 0° to 85°C Ambient operating temperature
