描述
The 8P34S2108-1 is a differential dual 1:8 LVDS output 1.8V/2.5V fanout buffer that boasts high performance and low power consumption. It is engineered to support fail-safe operation and is specifically designed for the fanout of high-frequency clock and data signals with very low additive phase noise. The device comprises two independent buffer channels, and each of these channels has eight outputs with low skew. High isolation between the channels ensures minimal noise coupling.
The 8P34S2108-1 shines in clock distribution applications that require well-defined performance and repeatability due to its guaranteed output-to-output and part-to-part skew characteristics. The device can operate using a 1.8V or 2.5V power supply. Its integrated bias voltage references allow for the easy interfacing of AC-coupled signals with the device's inputs.
The 8P34S2108-1 had the individual OE/Swing control pin for each output, which provides excellent control over both swing and output enable functions.
