DESCRIPTION The ABE0113 is a Spread Spectrum Clock Generator designed for the purpose of reducing EMI in highspeed digital systems. The selectable Down Spread modulation magnitude (see table below) permits EMI reduction without over-clocking the output. The device operates over a very wide range of input frequencies and provides 1x to 4x modulated clock outputs.
