700MHZ, CRYSTAL OSCILLATOR-TO-DIFFERENTIAL

LVDS FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS8442I is a general purpose, dual output • Dual differential LVDS outputs

ICS

Crystal-to-Differential LVDS High Frequency

• Selectable crystal oscillator interface or

LVCMOS/LVTTLTEST_CLK

HiPerClockS™

Synthesizer and a member of the HiPerClockS™

family of High Performance Clock Solutions from

ICS. The ICS8442I has a selectable TEST_CLK

• Output frequency range: 31.25MHz to 700MHz

• Crystal input frequency range: 10MHz to 25MHz

• VCO range: 250MHz to 700MHz

or crystal input. The TEST_CLK input accepts LVCMOS or

LVTTL input levels and translates them to LVDS levels. The

VCO operates at a frequency range of 250MHz to 700MHz.

The VCO frequency is programmed in steps equal to the value

of the input reference or crystal frequency.TheVCO and output

frequency can be programmed using the serial or parallel

interface to the configuration logic. The low phase noise

characteristics of the ICS8442I makes it an ideal clock source

for Gigabit Ethernet and Sonet applications.

• Parallel or serial interface for programming counter

and output dividers

• RMS period jitter: 3.5ps (typical)

• Cycle-to-cycle jitter: 18ps (typical)

• 3.3V supply voltage

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