Features
Description
Three PLLs with deep reference, feedback, post dividers provide precision clock frequencies Multiple outputs provide several clocking options Outputs individually tristated board testing OE_x pins SUSPEND# completely powers down entire device Package: 16-pin, 5.3mm (0.209") SSOP Custom frequency patterns, pinouts, packages available. Contact your local Sales Representative more information.
FS6312 ROM-based CMOS clock generator designed minimize cost component count variety electronic systems. Three low-jitter phase-locked loops (PLLs) drive five clock outputs provide high degree flexibility. device packaged 16-pin SOIC minimize board space. High-resolution divider capability permits generation desired frequencies.
