Description

The 8SLVP1212 is a high-performance, 12 output differential

LVPECL fanout buffer. The device is designed for the fanout of

high-frequency, very low additive phase-noise clock and data signals.

The 8SLVP1212 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 8SLVP1212 ideal for those clock distribution

applications demanding well-defined performance and repeatability.

Two selectable differential inputs and twelve 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.
