Description
The NB4N441 is a precision clock synthesizer which generates a
differential LVPECL clock output frequency from 12.5 MHz to
425 MHz. A Serial Peripheral Interface (SPI) is used to configure the
device to produce one of sixteen popular standard protocol output
frequencies from a single 27 MHz crystal reference. The NB4N441
also has the added feature of allowing application specific output
frequencies from 12.5 MHz to 425 MHz using crystals within the
range of 10 MHz to 28 MHz.
