Description
The PI90LV14 implements low voltage differential signaling (LVDS) to achieve clocking rates as high as 320MHz with low skew.
The PI90LV14 is a low-skew 1:5 clock distribution chip which incorporates multiplexed clock inputs to allow for distribution of a lower-speed, single-ended clock or a high-speed system clock. When LOWthe SEL pin will select the differential clock input.
