260MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL

LVPECL FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS84321I is a general purpose, dual output • Dual differential 3.3V LVPECL outputs

ICS

Crystal-to-3.3V Differential LVPECL High Fre-

quency Synthesizer and a member of the

HiPerClockS™ family of High Performance Clock

Solutions from ICS. The ICS84321I has a select-

• Selectable crystal oscillator interface

or LVCMOS/LVTTLTEST_CLK

HiPerClockS™

• Output frequency range: 103.3MHz to 260MHz

• Crystal input frequency range: 14MHz to 40MHz

• VCO range: 620MHz to 780MHz

able TEST_CLK or crystal inputs. The VCO operates at a fre-

quency range of 620MHz to 780MHz. The VCO frequency is

programmed in steps equal to the value of the input reference

or crystal frequency. The VCO and output frequency can be

programmed using the serial or parallel interfaces to the con-

figuration logic. The low phase noise characteristics of the

ICS84321I make it an ideal clock source for Fibre Channel 1,

Fibre Channel 2, 10 Gigabit Fibre Channel, Gigabit Ethernet

and 10 Gigabit Ethernet applications.

• Parallel or serial interface for programming counter

and output dividers

• RMS period jitter: 3ps (typical)

• RMS phase jitter at 155.52MHz, using a 38.88MHz crystal

(12KHz to 20MHz): 2.5ps (typical)

Phase noise: 155.52MHz
