General Description

The IDT8SLVD1208I is a high-performance differential LVDS fanout

buffer. The device is designed for the fanout of high-frequency, very

low additive phase-noise clock and data signals. The

IDT8SLVD1208I is characterized to operate from a 2.5V power

supply. Guaranteed output-to-output and part-to-part skew

characteristics make the IDT8SLVD1208I 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 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.
