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

? 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
