Microsemi Continues its Leadership in Timing Solutions by Unveiling Ultra-low Jitter and Ultra Small Size Clock Management Devices

ALISO VIEJO, CA -- Microsemi Corporation announces its new ZL30250 and ZL30251 flexible clock generators. The devices are an ultra-low jitter solution (160fs [12kHz-20MHz integration band]) in a 5x5mm package capable of replacing multiple high performance crystals and crystal oscillators, thus lowering bill of material (BOM) cost along with easing design and testing of timing solutions.

Microsemi continues its leadership by complementing its timing portfolio with these new high performance devices, enabling Microsemi to expand its overall market opportunity in enterprise networking as well as in storage area networks. According to Infonetics the enterprise switch market will grow to approximately $25 billion by 2018.

"The release of the ZL30250 and ZL30251 strengthens our leadership position as the providers of the most comprehensive and advance communication timing solutions that enable us to target new markets such as enterprise networking and storage," said Maamoun Seido, vice president and business unit manager of Microsemi's timing products. "With our new ultra-low jitter clock generators, we can now enable enterprise customers to meet aggressive performance standards imposed by key PHY vendors with the right cost and performance solution."

The ZL30250 and ZL30251 clock generators leverage Microsemi's long history of expertise in providing clock management solutions and now provide designers with an industry leading solution for applications in wired and wireless communication equipment, enterprise switch and routers, enterprise networks, storage area networks, along with industrial automation.

About the ZL30250 and ZL30251

Microsemi's new platform on the ZL30250 and ZL30251 is very flexible with highly configurable outputs and offers automatic self-configuration at power-up. This supports up to four different configurations easily selected using two device pins. This flexibility includes:

• Any-to-any frequency conversion with 0 ppm error (inputs: 10MHz-1.25GHz, outputs: 1Hz-1GHz)
• Three universal clock inputs connect to any signal format at any voltage
• Up to three differential outputs, up to six CMOS outputs
• Configurable output signal format and voltage for direct interface without additional components

The ZL30250 and ZL30251 offer numerically controlled oscillator (NCO) mode in which output frequencies can be controlled with very high resolution by system software. This capability allows the devices to replace solutions using large, expensive, fixed-frequency voltage-controlled oscillators (VCXOs) with a small, low-cost, any-frequency solution.

The ZL30250 and ZL30251 can generate PCI Express (PCIe) clock signals with or without spread-spectrum modulation required in server, storage and communication equipment allowing system designers to comply with EMI requirements.

As with all Microsemi clock generation and timing ICs, the ZL30250 and ZL30251 can be combined with Microsemi's high-performance fan-out buffers to provide complete timing solutions for complex systems. In addition, the ZL30250 and ZL30251 can accept clock signals from other Microsemi timing ICs, perform frequency conversion and output additional clock signals needed for the system design. These devices are flexible building-blocks that system designers can reuse over and over in various parts of a system design and across multiple designs.
