I
Crystal input to be connected to fundamental parallel mode crystal.(CL=18pF) or
clock input.
XOUT/SD

B
At power-up, this pin is an input pin to select modulation type. After input
sampling, this pin is crystal output. Has internal pull up resistor.

I
Digital control input to select modulation magnitude. Has internal pull-up.

P
Ground.
FOUT

O
Modulated Clock Frequency Output. The frequency before modulation is
synthesized by multiplying the input frequency by 1X, 2X, 4X, 6X depending on
the part number (ABE0101, 02, 04, 06).
SC2

Power Supply.
FUNCTIONAL DESCRIPTION
Selectable spread spectrum and modulation magnitudes
The ABE0101/02/04/06 provides selectable spread spectrum modulation type, as well as selectable modulation
magnitude. Selection is made by connecting specific pins to a logical “zero” or “one” according to the output clock
selection table on page 1.
In order to reduce the number of pins on the chip, the ABE0101/02/04/06 uses pin 2 (XOUT/SD) as a bi-directional
pin. The pin serves as modulation type selector input (SD) upon power-up (see output clock selection table on
page 1), and as XOUT crystal connection as soon as the input has been latched.
Pins 3 (SC0), 4 (SC1), and 7 (SC2) are used as inputs to select the spread spectrum modulation magnitude as
shown on the output clock selection table (page 1).
