DATA SHEET
General 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.
