Microsemi Corporation's 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.
The release of the ZL30250 and ZL30251 strengthens its 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.
With this new ultra-low jitter clock generators, Microsemi 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.
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.
