700MHZ, LOW JITTER, CRYSTAL-TO-3.3V

DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER

GENERAL DESCRIPTION

ICS

The ICS84330 is a general purpose, single output

high frequency synthesizer and a member of the

HiPerClockS™ HiPerClockS™ family of High Performance Clock

Solutions from ICS. The VCO operates at a fre-

quency range of 250MHz to 700MHz. The VCO and

output frequency can be programmed using the serial or parallel

interfaces to the configuration logic. The output can be config-

ured to divide the VCO frequency by 1, 2, 4, and 8. Output fre-

quency steps from 250KHz to 2MHz can be achieved using a

16MHz crystal depending on the output divider setting.
