The MX55/MX57 product line is an ultra-low jitter family
of industry standard crystal oscillators (XO) designed to
maximize performance in networking, storage, server,
and telecommunications equipment.
The MX55 employs a space-saving 3.2 mm x 5 mm
package, while the MX57 is in a 5 mm x 7 mm package.
These devices meet ±50 ppm total stability across
–40°C to +85°C operating temperature range, using
proven high reliability assembly methods that improve
long term reliability and minimize aging drift compared
to traditional XO assembly processes.
With programmable output format and OE options,
these XOs can be configured to be footprint compatible
with any standard 6-pin XO available today. Standard
options and frequencies are also available.
