FS6322-04 AMERICAN MICROSYSTEMS, INC. Three-PLL Clock Generator IC April 2000 1.0 • • • • • • • Features 2.0 Description 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 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 Representative for more information. The FS6322 is a ROM-based CMOS clock generator IC designed to minimize cost and component count in a variety of electronic systems. Three low-jitter phase-locked loops (PLLs) drive up to five low-skew clock outputs to provide a high degree of flexibility. The device is packaged in a 16-pin SOIC to minimize board space. High-resolution divider capability permits generation of desired frequencies.
