Description
The 8P34S1208-1 is a high-performance differential LVDS fanout buffer. The device is designed for the fanout of 1PPS signals or high-frequency, very low additive phase-noise clock and data signals.
The 8P34S1208-1 supports fail-safe operation and is characterized to operate from a 1.8V or 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the device ideal for clock distribution applications that demand 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.
The 8P34S1208-1 has an individual OE control pin for each output, which provides excellent control over the output enable functions.
