ICS843404

LVCMOS/CRYSTAL-TO-3.3V LVPECL AND

LVDS CLOCK GENERATOR

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

The ICS843404 is a low phase noise Fibre

• Three banks of outputs: one bank of two LVDS outputs

and two banks of one LVPECL output

ICS

Channel Clock Generator and is a member of

the HiPerClockS^TMfamily of high performance

clock solutions from ICS. The device provides

two banks of one LVPECL output per bank and

HiPerClockS™

• Selectable crystal oscillator interface or

LVCMOS/LVTTL single-ended reference clock input

one bank of two LVDS outputs. Each bank can be

independently set by using their respective frequency select

pins for the following output frequencies: 318.75MHz,

212.5MHz, 159.375MHz or 106.25MHz, using a 25.5MHz

18pF parallel resonant crystal. The ICS843404 can also be

driven from a 25.5MHz single-ended reference clock. For

system debug or test purposes, the PLL can be bypassed

using the VCO_SEL pin.

• Four independently selectable output frequency on each

bank: 318.75MHz, 212.5MHz, 159.375MHz and 106.25MHz

• Maximum output frequency: 318.75MHz

• Crystal input frequency: 25.5MHz

• V_DDO_LVPECL can be set for 3.3V or 2.5V, allowing the

device to generate 3.3V or 2.5V LVPECL levels

• RMS phase jitter at 106.25MHz, using a 25.5MHz crystal

(637kHz to 10MHz intergration): 2.65ps (typical)
