Description
The 8P34S2104 is a high-performance, low-power, differential dual 1:2 LVDS output, 1.8V/2.5V fanout buffer. The device supports fail-safe operation and 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 four 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 8P34S2104 ideal for those clock distribution applications demanding well-defined performance and repeatability. The device is characterized to operate from a 1.8V or a 2.5V power supply. The integrated bias voltage references enable easy interfacing of AC-coupled signals to the device inputs.
