10101 (For use in Pierce Oscillator Circuits)

CX1V CRYSTAL
10 kHz to 600 kHz
Miniature Quartz Crystal for Pierce Oscillators
DESCRIPTION
The CX1V quartz crystal is a high-quality tuning fork
resonator for use in Pierce (single inverter) oscillators. The
CX1V is hermetically sealed in a rugged, miniature ceramic
package, one-fourth the size of an eight-pin mini-DIP. The
CX1V crystal is manufactured using the STATEK-developed
photolithographic process, and was designed utilizing the
experience acquired by producing millions of crystals for
industrial, commercial, military and medical applications.

PACKAGE HANDLING
TYP.
The CX crystal is hermetically sealed in a ceramic package.
Normal handling and soldering precautions for small, low
thermal mass parts are adequate when installing or testing CX
crystals. CX crystals may be wave soldered, with proper
precaution taken to avoid desoldering the leads. A slow
machine rate or too high a pre-heat temperature or solder
bath temperature can damage the crystals. Lead to
package solder interface temperature should not
exceed 200oC for RoHS compliant version and 175oC
for non-RoHS version, glass lid to package seal rim
temperature should not exceed 210oC. If the seal rim
reaches temperatures above the maximum specified, the
package may lose its hermeticity. Loss of hermeticity results
in a frequency decrease and motional resistance increase.
