Multiplier Select Pin 1. Determines CLK output. Has internal pull-up.
Crystal input to be connected to 10-27MHz fundamental parallel mode crys-
tal (C
L
=15pF). On chip load capacitors: No external capacitor required.
Multiplier Select Pin 2. Determines CLK output. Has internal pull-up.
Multiplier Select Pin 3. Determines CLK output. Has internal pull-up.
Multiplier Select Pin 0. Determines CLK output. Has internal pull-up.
Output Enable. Tri-state CLK and REFOUT when low. Has internal pull-up.
Buffered crystal oscillator clock output. Controlled by REFEN.
Ground.
