PI90LV211Q集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

描述 Description

The PI90LV211 implements low voltage differential signaling (LVDS) to achieve clocking rates as high as 320 MHz with low skew. The PI90LV211 is a low skew 1:6 fanout device designed explicitly for low

skew clock distribution applications. The device features a multiplexed clock input to allow for the distribution of a lower speed scan or test clock with the high-speed system clock. When LOW the SEL

pin will select the differential clock input.
