Locked Loop techniques to allow the user to select
the desired multiplier value. The chip accepts crystal
or clock inputs ranging from 10 to 30MHz, depening
on selected multiplier, and produces outputs clocks
up to 198MHz at 3.3V.

Description
Clock output from VCO. Equals the input frequency times multiplier.
Reference clock enable. When Low, it turns off REFOUT.
3.3V Power Supply.
Crystal input to be connected to 10-30MHz fundamental parallel mode crys-
tal (C
L
=15pF). On chip load capacitors: No external capacitor required.
Crystal Connection.
Output Enable. Tri-state CLK and REFOUT when low. Has internal pull-up.
Buffered crystal oscillator clock output. Controlled by REFEN.
Multiplier Select Pin 0. Determines CLK output. Has internal pull-up.
Multiplier Select Pin 1. Determines CLK output. Has internal pull-up.
Multiplier Select Pin 1. Determines CLK output. Has internal pull-up.
Multiplier Select Pin 3. Determines CLK output. Has internal pull-up.
