4. Applications of the Si5338
Because of its flexible architecture, the Si5338 can be
configured to serve several functions in the timing path.
The
following
sections
describe
some
common
applications.
4.1. Free-Running Clock Generator
Using the internal oscillator (Osc) and an inexpensive
external crystal (XTAL), the Si5338 can be configured
as a free-running clock generator for replacing high-end
and long-lead-time crystal oscillators found on many
printed circuit boards (PCBs). Replacing several crystal
oscillators with a single IC solution helps consolidate the
bill of materials (BOM), reduces the number of
suppliers, and reduces the number of long-lead-time
components on the PCB. In addition, since crystal
oscillators tend to be the least reliable aspect of many
systems, the overall FIT rate improves with the
elimination of each oscillator.
Up to four independent clock frequencies can be
generated at any rate within its supported frequency
range and with any of supported output types. Features,
such as frequency increment and decrement and phase
adjustments
on
a
per-output
basis,
provide
unprecedented flexibility for PCB designs. Figure 17
shows the Si5338 configured as a free-running clock
generator.
