2.0 Description

The FS6206 is a monolithic CMOS clock generator IC

designed to minimize cost and component count.

An on-chip crystal oscillator generates the reference fre-

quenc y and t wo p has e-l oc ked loops are used to gener ate

precise output / reference frequency ratios. See Table 1

for information on the frequency ratios programmed into

each version of the FS6206.
