FUNCTIONAL DESCRIPTION
Selectable spread spectrum and modulation rates
The PLL701-13 provides selectable multiplication factor, as well as selectable modulation rate. Selection is made
by connecting pins 2 (S2), 3 (S1), 4 (S0), and 7 (S3) to a logical “zero” or “one”, according to the output clock
selection table on page 1.
Default values for S(0:3) through internal pull-up and pull-down resistor
Selection pins S0 and S3 have an internal pull-down resistor of 30kΩ, pins 2 and 3 (S1 and S2) have an internal
pull-up resistor of 30kΩ. This internal pull-down (or pull-up) resistor will pull the input value to a logical “zero” (or
“one” respectively) by default, i.e. when the pin is not connected to GND (VDD respectively). In order to override
the internal pull-up (pull-down), the pin has to be connected to VDD (GND respectively).
