New Solutions Support Industry's Lowest Additive Jitter Combined with Best Power Supply Noise Rejection Performance

ALISO VIEJO, Calif., Dec. 5, 2012 — (PRNewswire) — Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today expanded its communications timing portfolio with its first family of clock distribution differential fan-out buffers. The 28-part family of buffers supports clock rates of up to 750 megahertz (MHz); two types of outputs, low voltage positive emitter coupled logic (LVPECL) and low voltage differential signaling (LVDS); and multiple fan-out ratios. Internal and external terminations for inputs eliminate the need for external peripheral components. In addition, the ultra-low additive output jitter leaves the majority of the jitter budget to the high speed transceivers. The combination of these features results in lower bill-of-material (BOM) costs.

The new clock buffers devices are synergistic with Microsemi's broad timing portfolio and, when used together, provide customers improved board performance and complete timing solutions.

"Broadening our current timing and synchronization offering with our new buffer family allows us to offer customers a complementary building block for clock generation and synthesis products," said Maamoun Seido, vice president and business unit manager of Microsemi's timing products. "Communications is a key area of focus for Microsemi. With our investments in this area, including the acquisition of Maxim's timing, synthesis and synchronization business earlier this year, we now have the roadmaps and resources in place to capitalize on growing opportunities in this market segment."

About Microsemi's New Buffer Family

Microsemi's high-performance buffers deliver the industry's lowest additive jitter combined with best power supply noise rejection performance. This preserves signal integrity by adding ultra-low jitter and filtering noise from power supplies, resulting in better performance while simplifying engineering board design efforts. In addition, the flexible I/O structure and internal on chip input terminations eliminate the need for external components, which reduces BOM costs. Microsemi's new buffer family includes:

LVPECL Output Solutions:

LVDS Output Solutions:

Microsemi is the market leader in network synchronization and offers an industry-leading portfolio focused on timing solutions for packet networks (SyncE and IEEE1588) and optical transport network (OTN) systems. The company offers a complete portfolio of timing products for high-performance network synchronization including digital phase locked loop (DPLL) solutions to drive network clocks, as well as analog and mixed-signal timing ICs to meet performance requirements for up to 10G/40G interfaces.
