8P34S2108

Dual 1:8 LVDS Output 1.8V Fanout Buffer 8P34S2108 Datasheet Description The 8P34S2108 is a high-performance, low-power, differential dual 1:8 LVDS output 1.8V fanout buffer. The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. Two independent buffer channels are available, each channel has two low skew outputs. High isolation between channels minimizes noise coupling. AC characteristics such as propagation delay are matched between channels. Guaranteed output-to-output and part-to-part skew characteristics make the 8P34S2108 ideal for those clock distribution applications demanding well-defined performance and repeatability. The device is characterized to operate from a 1.8V power supply. The integrated bias voltage references enable easy interfacing AC-coupled signals to the device inputs.
