Overview
Description
The 8P34S2106A is a high-performance, low-power, differential dual 1:6 LVDS output 1.8V/2.5V fanout buffer. The device is designed for the fanout of high-frequency, very-low additive phase noise clock and data signals. Two independent buffer channels are available, each channel has six low-skew outputs. High isolation between channels minimizes noise coupling. AC characteristics such as propagation delay are matched between channels. Guaranteed output-to-output and part-to-part skew characteristics make the 8P34S2106A ideal for clock distribution applications demanding well-defined performance and repeatability. The device is characterized to operate from a 1.8V/2.5V power supply. The integrated bias voltage references enable easy interfacing of AC-coupled signals to the device inputs. The device supports fail-safe operation, it can handle DC levels up to 2.5V on its input pins while the device is powered down with very low leakage currents and doesn’t impact long-term reliability.
