General Description

The IDT8SLVP2102I 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 IDT8SLVP2102I 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 IDT8SLVP2102I ideal for those clock distribution applications demanding 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.
