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.
