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-

quency and two phase-locked loops are used to generate

precise output / reference frequency ratios. See Table 1

for information on the frequency ratios programmed into

each version of the FS6206.
