描述 Description

The 8SLVD1212 is a high-performance differential LVDS fanout

buffer. The device is designed for the fanout of high-frequency,

very low additive phase-noise clock and data signals.

The 8SLVD1212 is characterized to operate from a 2.5V power

supply. Guaranteed output-to-output and part-to-part skew

characteristics make the device ideal for clock distribution

applications that demand well-defined performance and

repeatability.

Two selectable differential inputs and twelve low skew outputs are

available. The integrated bias voltage reference enables easy

interfacing of single-ended signals to the device inputs.

The 8SLVD1212 is optimized for low power consumption and low

additive phase noise.
