Contact your local AMI Sales Representative for more information. Description 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.
