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.
