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
