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
