The 8T53S111I 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 8T53S111I 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 8T53S111I ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and ten low skew outputs are available. The integrated VREF voltage generator enables easy interfacing of single-ended signals to the device inputs. The device is optimized for low power consumption and low additive phase noise.
