General Description

The ICS854110I is a high-performance differential LVDS clock fanout

buffer. The device is designed for signal fanout of high-frequency, low

phase-noise clock signals. The selected differential input signal is

distributed to ten differential LVDS outputs. The ICS854110I is

characterized to operate from a 2.5V power supply. Guaranteed

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

ICS854110I ideal for those clock distribution applications demanding

well-defined performance and repeatability. The device offers an

output slew rate control with four pre-set output transition times to

solve crosstalk and EMI problems in complex board designs. A

fail-safe input design forces the outputs to a defined state if

differential clock inputs are open or shorted, see Table 3D.
