3.3V VCXO and Low Noise PLL Clock Generator

��

Description

The PI6CX230B is a 3.3V ±5% VCXO and low phase noise 8x

PLL clock generator available in discrete IC form with external

SaRonix crystal. The PI6CX230B features a low-noise 8x clock

multiplication circuit with improved phase noise performance and

LVCMOS output clock signal. The device accepts an external

analog control voltage signal that pulls the output frequency

by ±150 ppM. Contact Pericom/SaRonix for recommended

crystal specifications. For applications that require LVDS output

compatibility, see the PI6CX231A/B.
