MX55/MX57
DESCRIPTION
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. With typical phase jitter ranges from 160fs to
230fs depending on output format, output frequency, and package, these devices
improve signal-to-noise ratio and bit error rate in high line rate applications such
as 10/40/100GEthernet, optical communications, PCI Express, Fibre Channel/SAS,
CPRI/OBSAI, XAUI, and backplane SERDES links.
The MX55 is an industry leading ultra-low jitter XO family available in a
3.2mm x 5mm package. The MX57 is an industry leading ultra-low jitter XO available
in 5mm x 7mm package. These devices meet ±50ppm total stability across the
-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 6-pin XO available today. Standard options and
frequencies are available and additional options and frequencies can be requested
using the online configuration tool http://clockworks.micrel.com/micrel.
