SAN JOSE, CA--(Marketwired - May 6, 2014) - Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today introduced the MX55/57 FUSION, crystal oscillator clock (XO) solutions. These devices offer industry-leading phase jitter performance of 170fsrms (12kHz to 20MHz) in standard 5mm x 7mm or 3.2mm x 5mm footprint. These XOs target a broad range of frequencies up to 840MHz and support standard frequencies for applications including 10/40/100G Ethernet, optical communications, SAS and PCI express. All options are available in volume quantities and short lead times, with pricing below $10.00 for 1,000 quantities for most configurations. For samples, please contact your local distributor or use the Micrel ClockWorks Configurator web tool: http://clockworks.micrel.com/micrel.

"The MX55/57 family is designed to maximize performance in networking, storage, server and telecommunications equipment," noted Rami Kanama, vice president, timing and communications business group, Micrel. "The ultra-low jitter improves design margins, enhances signal-to-noise-ratios and helps minimize bit error rates. These products provide a broad range of programmable options to meet designers' every need."

The MX55/57 family offers a compelling high power supply noise immunity enabled by on-chip linear regulators that improve overall performance in noisy environments. The devices support 3.3V or 2.5V supply and LVPECL, LVDS, CMOS and HCSL output logic formats. These devices meet +50ppm total stability including aging and temperature drift across a -40C-deg to +85C-deg operating temperature range. The use of a proven plastic molded assembly improves long term reliability and minimizes aging drift compared to traditional XO devices. Finally, all options are available in a compact 3.2mm x 5mm package for the MX55 product family that reduces costly board space, a key concern for high channel density applications. The MX57 family of solutions comes in an easy-to-design 5mm x 7mm package option.
