Low Phase Noise, Dual 1-to-8, 3.3V,
2.5V LVPECL Output Fanout Buffer
8SLVP2108
Datasheet
General 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.
