概要

説明

The 8P34S1204 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 8P34S1204 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 8P34S1204 ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and four 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.

The 8P34S1204-1 has an individual OE control pin for each output, which provides excellent control over the output enable functions.
