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.
