GENERAL DESCRIPTION

FEATURES

The ICS8430-71 is a general purpose, dual output • Dual differential 3.3V LVPECL outputs

ICS

Crystal/LVCMOS-to-3.3V Differential LVPECL High

• Selectable crystal oscillator interface

Frequency Synthesizer and a member of the

or LVCMOS TEST_CLK

HiPerClockS™

HiPerClockS™family of High Performance Clock

Solutions from ICS.The ICS8430-71 has a select-

• Output frequency up to 700MHz

able crystal oscillator interface or LVCMOS TEST_CLK. The

VCO operates at a frequency range of 250MHz to 700MHz.

With the output configured to divide the VCO frequency by 2,

output frequency steps as small as 2MHz can be achieved using

a 16MHz crystal or test clock. Output frequencies up to 700MHz

can be programmed using the serial or parallel interfaces to the

configuration logic. The low jitter and frequency range of the

ICS8430-71 make it an ideal clock generator for most clock

tree applications.

• Crystal input frequency range: 12MHz to 27MHz

• VCO range: 250MHz to 700MHz

• Parallel or serial interface for programming counter

and output dividers

• RMS period jitter: 9ps (maximum)

• Cycle-to-cycle jitter: 25ps (maximum)

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
