AV9110
Pin Configuration
Clock Reference Implementations:
AV9110-01 vs. AV9110-02
The
AV9110
requires a stable reference clock (5 to 32 MHz) to
generate a stable, low jitter output clock. The
AV9 11 0 -01
is
optimized to use an external quartz crystal as a frequency
reference, without the need of additional external components.
The AV9110-02 is optimized to accept an TTL clock
reference. Either device can be used with an external crystal
or accept a TTL clock reference, although extra components
may be required. The various combinations implied are
summarized in Figure 2 (see page 7).
