Micrel Offers Highest Level of Clock Tree Integration With Revolutionary

Published:

SAN JOSE, CA -- (Marketwire) -- 11/08/12 -- Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance analog and high-speed mixed signal, LAN, and timing and communications solutions, announces ClockWorks Fusion, a revolutionary clock generation product family from Micrel that integrates the crystal, frequency synthesizer and fan-out buffer to deliver industry-leading integration in a single package. The MX85 is the first in a series of devices aimed at simultaneously meeting the ultra-low jitter (less than 200fs) and integration requirements of 10/40/100 Gigabit Ethernet, PCIe 2.0/3.0, Fibre Channel, SAS/SATA, and high speed reference clocking for FPGA and SerDes applications. Integrating the crystal in a compact package provides a complete clocking solution that eliminates the design burden imposed by existing discrete solutions. With jitter performance accounting for on-chip fan-out buffers, this custom configurable (OTP) clocking solution reduces customers' bill-of-material (BOM) and footprint, simplifies PCB design, and enhances overall system performance. The MX85 can be configured with up to five outputs of two different frequencies supporting LVPECL, LVDS, HCSL and CMOS logic types.

"ClockWorks Fusion represents the next step in our Clock and Timing strategy of delivering the industry's highest level of performance and integration," stated Rami Kanama, vice president for the Timing and Communications Division at Micrel. "With jitter budgets tightening and design cycles shortening, many end system designers can no longer rely on disjointed clock trees that degrade performance and increase design complexity. The OTP configurable MX85 resolves these challenges by leading the industry with a complete clock tree solution in a single small package."

MX85xxx products supporting the most common communications frequencies are sampling now in a space saving 5mm x 7mm LGA. Pricing is dependent upon configuration.
