Description

The 8SLVS1118 is a high-performance, low-power, differential

1:18 output fanout buffer. This highly versatile device is designed

for the fanout of high-frequency, very low additive phase-noise

clock and data signals. Guaranteed output-to-output and

part-to-part skew characteristics make the 8SLVS1118 ideal for

clock distribution applications that demand well-defined

performance and repeatability.

The device is characterized to operate from a 2.5V or 3.3V power

supply. The integrated bias voltage references enable easy

interfacing AC-coupled signals to the device inputs.
