low phase noise clock synthesizer with 4x or 8x mul-
tiplier. Using Abracon’s proprietary analog and digi-
tal Phase Locked Loop techniques, this IC can pro-
duce up to a 160MHz out put. Ideal for 155.52MHz
applications.

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.
Ground.
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.
