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.
