General Description

The 8SLVP1208 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 8SLVP1208 is

characterized to operate from a 3.3V and 2.5V power supply.

Guaranteed output-to-output and part-to-part skew characteristics

make the 8SLVP1208 ideal for those clock distribution applications

demanding well-defined performance and repeatability. Two

selectable differential inputs and eight low skew outputs are

available. The integrated bias voltage generators enables easy

interfacing of single-ended signals to the device inputs. The device is

optimized for low power consumption and low additive phase noise.
