• S0, S1, and S2 inputs modify output frequencies for
design flexibility
• 3.3V operation
• Accepts 5 to 30MHz crystals (see Frequency Table
for specific reference frequencies required)
• Custom frequency patterns, pinouts, and packages
are available. Contact your local AMI Sales Repre-
sentative for more information.
2.0 Description
The FS6322 is a ROM-based CMOS clock generator IC
designed to minimize cost and component count in a va-
riety of electronic systems.
Three low-jitter phase-locked loops (PLLs) drive up to five
low-skew clock outputs to provide a high degree of flexi-
bility. The device is packaged in a 16-pin SOIC to mini-
mize board space.
High-resolution divider capability permits generation of
desired frequencies.
