Description
The 8P34S1102 is a high-performance differential LVDS fanout buffer. The device is designed for the fanout of 1PPS signals or high-frequency, very low additive phase noise clock and data signals. The 8P34S1102 supports fail-safe operation and is characterized to operate from a 1.8V or 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the 8P34S1102 ideal for those clock distribution applications demanding well-defined performance and repeatability. One differential input and two low skew outputs are available. The integrated bias voltage reference enables easy interfacing of single-ended signals to the differential device input. The device is optimized for low power consumption and low additive phase noise.
