Low EMI Spread Spectrum Multiplier Clock
Connecting a selection pin to a logical “one”
All selection pins have an internal pull-up resistor (30kΩ for pins 3, 4, 7, and 120kΩ for pin 2). This internal pull-up
resistor will pull the input value to a logical “one” (pull-up) by default, i.e. when no resistive load is connected
between the pin and GND. No external pull-up resistor is therefore required for connecting a logical “one” upon
power-up.
Connecting a selection pin to a logical “zero”
For an input only pin, i.e. pins 3 (SC0), 4 (SC1), and 7 (SC2), the pin simply needs to be grounded to pull the input
down to a logical “zero”. Connecting the bi-directional pin (SD) to a logical “zero” will however require the use of a
27kΩ loading resistor between the pin and GND.

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied.
* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.
