IDT's 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 2.5 V or 3.3 V power supply. The integrated bias voltage references enable easy interfacing AC-coupled signals to the device inputs.
