1.0 Features
• Three PLLs with deep reference, feedback, and post
dividers to provide precision clock frequencies
• Multiple outputs provide several clocking options
• Outputs may be tristated for board testing
• S0, S1, and S2 inputs modify output frequencies for
design flexibility
• 3.3V operation
• 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.
Thr ee low-jitter phase-locked loops (PL Ls ) driv e u p 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.
