Output Modulated Frequency
: Frequency modulated copy
of the unmodulated input clock (SSON# asserted).
CLKIN or X1

Crystal Connection or External Reference Frequency In-
put:
This pin has dual functions. It may either be connected
to an external crystal, or to an external reference clock.
NC or X2

I
Crystal Connection:
If using an external reference, this pin
must be left unconnected.
SSON#

I
Spread Spectrum Control (Active LOW):
Asserting this sig-
nal (active LOW) turns the internal modulation waveform on.
This pin has an internal pull-down resistor.

Frequency Selection Bit(s) 1 and 2:
These pins select the
frequency range of operation. Refer to
Table 2
. These pins
have internal pull-up resistors.

Modulation Width Selection:
When Spread Spectrum fea-
ture is turned on, this pin is used to select the amount of
variation and peak EMI reduction that is desired on the output
signal.
