• Outputs may be tristated for board testing

• S0, S1, and S2 inputs modify output frequencies for

design flexibility

• 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. The device is packaged in a 16-pin SOIC to mini-

mize board space.

High-resolution divider capability permits generation of

desired frequencies.
