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.
