DESCRIPTION
The PLL701-14 is a Spread Spectrum Clock
Generator designed to reduce EMI in high-speed
digital systems. Its spread spectrum modulation
amplitude is selectable via the input selector pins.
The chip multiplies any input from 10MHz to 30MHz
by 6x. The chip provides an output Enable/Disable
input permitting the user to tri-state the output.
