Description
The 8SLVP1204 is a high-performance differential LVPECL fanout
buffer. The device is designed for the fanout of high-frequency, very
low additive phase-noise clock and data signals. The 8SLVP1204 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 8SLVP1204 ideal for clock distribution applications that
demand well-defined performance and repeatability. Two selectable
differential inputs and four low skew outputs are available. The
integrated bias voltage reference enables easy interfacing of
single-ended signals to the device inputs. The device is optimized for
low power consumption and low additive phase noise.
