Description

The 8SLVP2108 is a high-performance differential dual 1:8

LVPECL fanout buffer. The device is designed for the fanout of

high-frequency, very low additive phase-noise clock and data

signals.

The 8SLVP2108 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 8SLVP2108 ideal for those clock

distribution applications demanding well-defined performance and

repeatability. Two independent buffers with eight low skew outputs

each are available. The integrated bias voltage references enable

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

device is optimized for low power consumption and low additive

phase noise.
