Product Description
The LX321 XO series is a high performance
CMOS crystal oscillator family with very low
jitter performance.
It supports 0.9V/1.0V/1.2V/1.5V voltages
and consumes very low operating current.
It is designed to meet the clock source
specifications for communication systems,
industrial applications and other high
performance equipment.
CREATED USING CADSTD LITE FREEWARE FROM WWW.CADSTD.COM. NON-COMMERCIAL USE ONLY.
