ICS84314

350MHZ, CRYSTAL-TO-3.3V/2.5V LVPECL

FREQUENCY SYNTHESIZER W/FANOUT BUFFER

GENERAL DESCRIPTION

The ICS84314 is a general purpose quad output

frequency synthesizer and a member of the

HiPerClockS™ family of High Performance Clock

Solutions from ICS. When the device uses par-

allel loading, the M bits are programmable and

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.
