1.0 Features
Three PLLs with deep reference, feedback, and post
dividers to provide precision clock frequencies
Multiple outputs provide several clocking options
Suspend feature shuts down a selection of PLLs and
outputs for power conservation
Outputs may be tristated for board testing
S0 and S1 frequency select inputs modify output fre-
quencies for design flexibility
Glitch-free slewing of CLK_CPU output enables
downstream PLLs to remain locked
5V to 3.3V operation
Accepts 5 to 30MHz crystals
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. A buffered copy of the reference clock is also avail-
able. The device is packaged in a 16-pin SOIC to mini-
mize board space.
