Clock Generators offer low jitter and power consumption.

Press Release Summary:



Intended for communications equipment, enterprise routers/switches, SAN equipment, and servers, dual-channel ZL30240 and single-channel ZL30241 generate output clocks with jitter as low as 0.27 psec (rms). Both consume <300 mW per channel and feature numerically controlled oscillators that can generate any frequency with fine tunability of 0.1 ppb. Products also feature 2–4 independently programmable outputs with support for multiple frequencies (up to 940 MHz) and multiple signal formats.

Microsemi Unveils New High-Performance Clock Management Semiconductor Timing Solutions



Clock Generators Feature Low Jitter, Low Power and NCO in a Small Package



ALISO VIEJO, Calif. -- Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today unveiled  the dual-channel ZL30240 and single-channel ZL30241 clock generators for multiple applications including communications equipment, enterprise routers and switches, storage area network equipment, and servers.



"With our new clock generators, designers no longer need to rely on expensive oscillators to get high speed output clocks with outstanding jitter performance, flexibility and dependable performance," said Maamoun Seido, vice president and business unit manager of Microsemi's timing products. "The addition of these new generators, coupled with the launch of our first clock buffer family last year, further solidifies our leadership position in timing and synchronization semiconductor solutions. This market segment remains a key area of focus and investment for Microsemi."



Market research firm Databeans estimates the clock generation integrated circuit market to be over $700 million in 2012.



Traditionally, fundamental speed oscillators have a limitation in the range of 50 megahertz (MHz) and third overtone options have a limitation  in the range of 150 MHz. Designers depend on analog phase locked loops (APLLs) to multiply low frequency signals and generate the desired high frequencies. The quality of the output signal depends on the performance of the APLL. To achieve high performance, designers are forced to use high cost APLLs, as high performance drives a higher APLL cost.



Microsemi's new, small footprint, high-performance clock generators can generate high frequency output clocks with very low jitter, low power consumption. The dual-channel or single-channel variants feature numerically controlled oscillators (NCO) that can generate any frequency with fine tunability of 0.1ppb (parts per billion). The new clock generators improve reliability, simplify product development efforts, lower bill-of-material costs and are well-suited for cost-sensitive applications with high performance requirements.



Microsemi's ZL30240 and ZL30241 feature several key attributes including:



--  Two to four independently programmable outputs with support for multiple frequencies (up to 940 MHz) and multiple signal formats to facilitate flexible rate conversions;

--  Up to two synthesizers enabling the concurrent use of two independent frequency families;

--  Jitter as low as 0.27 picoseconds (rms), meeting tight jitter budgets of PHYs;

--  Low power consumption (less than  300 milliwatts per channel); and

--  Space- and cost-savings 7 x 7 millimeter package.



Microsemi is a 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.  Microsemi's clock management solutions include clock generators and synthesizers, clock  fanout buffers, and rate conversion  jitter attenuators  that allow product developers to simplify system and board design.
