Description

The 8SLVP2104I is a high-performance differential dual LVPECL

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

very low additive phase-noise clock and data signals.

The 8SLVP2104I is characterized to operate from a 3.3V or 2.5V

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

characteristics make the 8SLVP2104I 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 enable

easy interfacing of single-ended signals to the device inputs. The

device is optimized for low power consumption and low additive

phase noise.
