854110I中文资料2.5V Differential LVDS Clock Buffer数据手册Renesas规格书

描述 Description

The 854110I 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 854110I is characterized to operate from a 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the 854110I 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.
