DESCRIPTION

The PLL701-21 is a Spread Spectrum Clock

Generator designed for the purpose of reducing EMI

in high-speed digital systems, with selectable Center

Spread modulation magnitude (see table below). The

device operates over a very wide range of input

frequencies and provides a 1x modulated clock

output.
