PRELIMINARY

ICS84314-02

Integrated

Circuit

Systems, Inc.

700MHZ, CRYSTAL-TO-3.3V/2.5V LVPECL

FREQUENCY SYNTHESIZER W/FANOUT BUFFER

FEATURES

GENERAL DESCRIPTION

• Fully integrated PLL

The ICS84314-02 is a general purpose quad

ICS

output frequency synthesizer and a member of

the HiPerClockS™family of High Performance

• Four differential 3.3V or 2.5V LVPECL outputs

HiPerClockS™

Clock Solutions from ICS.When the device uses • Selectable crystal oscillator interface

parallel loading, the M bits are programmable and

or LVCMOS/LVTTLTEST_CLK input

• Output frequency range: 31.25MHz to 700MHz

• VCO range: 250MHz to 700MHz

the output divider is hard-wired for divide by 2 thus providing

a frequency range of 125MHz to 350MHz. In serial program-

ming mode, the M bits are programmable and the output

divider can be set for either divide by 1, 2, 4 or divide by 8,

providing a frequency range of 31.25MHz to 700MHz.

Additionally, the device supports spread spectrum clocking

(SSC) for minimizing Electromagnetic Interference (EMI).The

low cycle-cycle jitter and broad frequency range of the

ICS84314-02 make it an ideal clock generator for a variety of

demanding applications which require high performance.

• Supports Spread Spectrum Clocking (SSC)

• Parallel interface for programming counter

and output dividers during power-up

• Serial 3 wire interface

• Cycle-to-cycle jitter: 20ps (typical)

• Output skew: TBD

• Output duty cycle: TBD

• Full 3.3V or mixed 3.3V core, 2.5V output operating supply

• 0°C to 85°C ambient operating temperature

• Available in both standard and lead-free RoHS-complaint
