8SLVP2106
DATA SHEET
General Description
The 8SLVP2106 is a high-performance differential dual 1:6 LVPECL
fanout buffer. The device is designed for the fanout of high-frequency,
very low additive phase-noise clock and data signals. The
8SLVP2106 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 8SLVP2106 ideal for those clock distribution
applications demanding well-defined performance and repeatability.
Two independent buffers with six 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.
