描述
The 8516 is a low skew, high performance 1-to-16 Differential-to-LVDS Clock Distribution Chip. The 8516 CLK, nCLK pair can accept any differential input levels and translates them to 3.3V LVDS output levels. Utilizing Low Voltage Differential Signaling (LVDS), the 8516 provides a low power, low noise, pointto- point solution for distributing clock signals over controlled impedances of 100?. Dual output enable inputs allow the 8516 to be used in a 1-to-16 or 1-to-8 input/output mode. Guaranteed output and part-to-part skew specifications make the 8516 ideal for those applications demanding well defined performance and repeatability.
