Pin Description
CLKOUT
8
O
Output Modulated Frequency
: Frequency modulated copy of the input clock
(SSON# asserted).
REFOUT
14
O
Non-Modulated Output:
This pin provides a copy of the reference frequency.
This output will not have the Spread Spectrum feature enabled regardless of
the state of logic input SSON#.
CLKIN or X1
2
I
Crystal Connection or External Reference Frequency Input:
This pin has
dual functions. It may either be connected to an external crystal, or to an
external reference clock.
NC or X2
3
I
Crystal Connection:
Input connection for an external crystal. If using an ex-
ternal reference, this pin must be left unconnected.
SSON#
12
I
Spread Spectrum Control (Active LOW):
Asserting this signal (active LOW)
turns the internal modulation waveform on. This pin has an internal pull-down
resistor.
SS%
6
I
Modulation Width Selection:
When Spread Spectrum feature is turned on,
this pin is used to select the amount of variation and peak EMI reduction that
is desired on the output signal. This pin has an internal pull-up resistor.
OE#
13
I
Output Enable (Active LOW):
When this pin is held HIGH, the output buffers
are placed in a high-impedance mode.This pin has an internal pull-down re-
sistor.
Reset
11
I
Modulation Profile Restart:
A rising edge on this input restarts the modulation
pattern at the beginning of its defined path. This pin has an internal pull-down
resistor.
FS1:2
7, 1
I
Frequency Selection Bit(s):
These pins select the frequency range of oper-
ation. Refer to
Table 2
. These pins have internal pull-up resistors.
VDD
9,10
P
Power Connection:
Connected to 3.3V or 5V power supply.
GND
4,5
G
Ground Connection:
Connect all ground pins to the common ground plane.
