ICS8427-02

500MHZ, LOW JITTER

LVCMOS/CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS8427-02 is a general purpose, six • Six differential LVHSTL outputs

ICS

HiPerClockS™

LVHSTL output high frequency synthesizer

• Selectable crystal input interface orTEST_CLK input

and a member of the HiPerClockS™ family of

High Performance Clock Solutions from ICS.

The ICS8427-02 can support a very wide

• TEST_CLK accepts the following input types:

LVCMOS, LVTTL

output frequency range of 15.625MHz to 500MHz. The

device powers up at a default output frequency of

200MHz with a 16.6667MHz crystal interface, and the

frequency can then be changed using the serial programm-

ing interface to change the M feedback divider and N

output divider. Frequency steps as small as 125kHz can

be achieved using a 16.6667MHz crystal and the output

divider set for ÷16.The low jitter and frequency range of the

ICS8427-02 make it an ideal clock generator for most

clock tree applications.

• Output frequency range: 15.625MHz to 500MHz

• VCO range: 250MHz to 500MHz

• Serial interface for programming feedback and output dividers

• Supports SSC, -0.5% downspread.Can be enabled through

use of the serial programming interface.

• Output skew: 100ps (maximum)

• Cycle-to-cycle jitter: 50ps (maximum)

• 2.5V core/1.8V output supply voltage

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request

• Available in both standard and lead-free RoHS-compliant

packages
