ICS8545BGI REV. B MARCH 02, 2009

General Description

The ICS8545I is a low skew, high performance

1-to-4 LVCMOS/LVTTL-to-LVDS Clock Fanout

Buffer and a member of the HiPerClockS™ family of

High Performance Clock Solutions from IDT.

Utilizing Low Voltage Differential Signaling (LVDS)

the ICS8545I provides a low power, low noise, solution for

distributing clock signals over controlled impedances of 100

Ω. The

ICS8545I accepts a LVCMOS/LVTTL input level and translates it

to 3.3V LVDS output levels.

Guaranteed output and part-to-part skew characteristics make the

ICS8545I ideal for those applications demanding well defined

performance and repeatability.

Features

• Four differential LVDS output pairs

• Two LVCMOS/LVTTL clock inputs to support redundant

or selectable frequency fanout applications

• Maximum output frequency: 650MHz

• Translates LVCMOS/LVTTL input signals to LVDS levels

• Output skew: 40ps (maximum)

• Part-to-part skew: 500ps (maximum)

• Propagation delay: 3.6ns (maximum)

• Additive phase jitter, RMS: 0.13ps (typical)

• Full 3.3Vsupply mode

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

• Available in both standard (RoHS 5) and lead-free (RoHS 6)
