FEATURES

• Low phase noise output for the 192MHz to

400MHz range (-134 dBc at 10kHz offset).

• PECL output.

• 12 to 25MHz crystal input.

• Integrated crystal load capacitor: no external

load capacitor required.

• Output Enable selector.

• 3.3V operation.

• Available in 16 Pin TSSOP.

DESCRIPTION

The ABX0213 is a monolithic low jitter and low

phase noise (-134dBc/Hz @ 10kHz offset) XO IC

with PECL output, for 192MHz to 400MHz output

range. It provides a low phase noise reference

frequency using a low cost crystal.

This makes the ABX0213 ideal for a wide range of

applications.
