GENERAL DESCRIPTION

The ICS843004I-04 is a 4 output LVPECL

Synthesizer optimized to generate clock

frequencies for a variety of high performance

applications and is a member of the

HiPerClocksTM family of high perfor mance

clock solutions from ICS. This device can select its input

reference clock from either a crystal input or a single-

ended clock signal. It can be configured to generate 4

outputs with individually selectable divide-by-one or

divide-by-four function via the 4 frequency select pins

(F_SEL[3:0]). The ICS843004I-04 uses ICS’ 3 rd

generation low phase noise VCO technology and can

achieve 1ps or lower typical r ms phase jitter. This

ensures that it will easily meet clocking requirements

for SDH (STM-1/STM-4/STM-16) and SONET (OC-3/

OC12/OC-48). This device is suitable for multi-rate and

multiple por t line card applications. The ICS843004I-04

is conveniently packaged in a small 24-pin TSSOP

package.

FEATURES

• Four LVPECL outputs

• Selectable crystal oscillator interface

or LVCMOS/LVTTL single-ended input

• Supports the following applications: SONET/SDH, SATA,

or 10Gb Ethernet

• Output frequency range: 140MHz - 170MHz,

560MHz - 680MHz

• VCO range: 560MHz - 680MHz

• RMS phase jitter @ 622.08MHz output, using a 19.44MHz

crystal (12kHz - 20MHz): 0.82ps (typical)

• RMS phase jitter @ 156.25MHz output, using a 19.53125MHz

crystal (1.875MHz - 20MHz): 0.57ps (typical)

• RMS phase jitter @ 155.52MHz output, using a 19.44MHz

crystal (12kHz - 20MHz): 0.94ps (typical)

• Full 3.3V supply mode

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

• Available in both standard and lead-free RoHS compliant

packages
