DESCRIPTION
The PLL701-17 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
multiplication factor can be selected from 4 multiplier
modes. The device operates over a wide range of
input frequencies and provides 1x, 2x. 2.94x and 4x
modulated clock outputs.
