LOW SKEW, 1-TO-4 LVCMOS/LVTTL-TO-LVDS

FANOUT BUFFER

ICS8545

Description

The ICS8545 is a low skew, high performance 1-to-4

LVCMOS/LVTTL-to-LVDS Clock Fanout Buffer and a

HiPerClockS™

member of the HiPerClockS™ family of High

Performance Clock Solutions from IDT. Utilizing Low

Voltage Differential Signaling (LVDS) the ICS8545

provides a low power, low noise, solution for distributing clock

signals over controlled impedances of 100Ω. The ICS8545

accepts a LVCMOS/LVTTL input level and translates it to 3.3V

LVDS output levels.

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

0°C to 70°C ambient operating temperature

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

packages

ICS

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

ICS8545 ideal for those applications demanding well defined

performance and repeatability.
