GENERAL DESCRIPTION

FEATURES

The ICS8402I is a general purpose, Crystal-to- • (2) LVCMOS/LVTTL outputs

ICS

LVCMOS/LVTTL High Frequency Synthesizer and

a member of the HiPerClockS™ family of High

or LVCMOS/LVTTL TEST_CLK

• Selectable crystal oscillator interface

HiPerClockS™

Performance Clock Solutions from ICS. The

ICS8402I has a selectable TEST_CLK or crystal

• Output frequency range: 15.625MHz - 350MHz

• Crystal input frequency range: 12MHz to 40MHz

• VCO range: 250MHz to 700MHz

inputs. The VCO operates at a frequency range of 250MHz

to 700MHz.TheVCO 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 configuration logic. The low

phase noise characteristics of the ICS8402I make it an ideal

clock source for Gigabit Ethernet and SONET applications.

• Parallel or serial interface for programming counter

and output dividers

• RMS period jitter: 30ps (maximum)

• Cycle-to-cycle jitter: 100ps (maximum)

• Full 3.3V or mixed 3.3V core/2.5V output supply voltage

• -40°C to 85°C ambient operating temperature

• Lead-Free fully RoHS compliant
