GENERAL DESCRIPTION
The ICS8431-01 is a general purpose clock frequency synthesizer for IA64/32 application and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8431-01 consists of one independent low bandwidth PLL timing channel. A 16.666MHz crystal is used as the input to the on-chip oscillator. The M is configured to produce a fixed output frequency of 200MHz.

FEATURES
• Fully integrated PLL
• Differential 3.3V LVPECL output
• 200MHz output frequency
• 48% to 52% duty cycle
• Crystal oscillator interface
• 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
• LVTTL / LVCMOS control inputs
• PLL bypass modes supporting in-circuit testing and on-chip functional block characterization
• 28 lead SOIC
• RMS cycle-to-cycle jitter of 2ps
• Typical cycle-to-cycle jitter of 18ps
• 0° to 85°C ambiant operating temperature
