FEATURES

GENERAL DESCRIPTION

• Fully integrated PLL

• 4 differential 3.3V or 2.5V LVPECL outputs

The ICS84314 is a general purpose quad output

ICS

frequency synthesizer and a member of the

HiPerClockS™ family of High Performance Clock

HiPerClockS™

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

allel loading, the M bits are programmable and

or LVCMOSTEST_CLK input

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 di-

vider can be set for either divide by 2 or divide by 4, providing

a frequency range of 62.5MHz to 350MHz. The low cycle-

cycle jitter and broad frequency range of the ICS84314 make

it an ideal clock generator for a variety of demanding applica-

tions which require high performance.

• Output frequency range: 62.5MHz to 350MHz

• VCO range: 250MHz to 700MHz

• Parallel interface for programming counter

and output dividers during power-up

• Serial 3 wire interface

• Cycle-to-cycle jitter: 23ps (typical)

• Output skew: 16ps (typical)

• Output duty cycle: 49% < odc < 51%, fout ≤ 125MHz

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

• 0°C to 85°C ambient operating temperature

• Lead-Free package available
