Microsemi has added three products to its portfolio of clock management solutions: the ZL30244 and ZL30245, two dual-channel any-to-any clock multiplier and frequency synthesiser ICs, and the ZL30255, a dual-channel any-to-any clock multiplier and jitter attenuator. Target applications for the devices include access networks, storage area networks, data centre infrastructure, enterprise infrastructure, and video broadcast equipment.

Designed for the communications, computing, enterprise and video markets, Microsemi’s clock management solutions also reduce board space requirements and lower implementation costs for designers. The ZL30244 and ZL30245 are suitable for frequency conversion and frequency synthesis, while the ZL30255 is designed for general purpose jitter attenuation and frequency conversion.

When combined with Microsemi fanout buffers (ZL402XX), the ZL30244/45 and ZL30255 provide complete timing solutions for complex systems such as wireless base stations, wireless backhaul, access infrastructure, SONET/ SDH, GE, 10G/40G/100G Ethernet, optical, storage and broadcast video applications.

“Our three clock management solutions build upon the success of Microsemi’s single-channel versions, ZL30250/251 and ZL30253, further expanding product capabilities for our customers to reduce design complexity and lower BOM costs,” said Maamoun Seido, Vice President and Business Unit Manager, Timing Products, Microsemi. “Providing the second channel in these devices further simplifies and reduces the cost of designs. For clock trees that require multiple frequency families, the ZL30244, ZL30245 and ZL30255 provide lower chip count and lower cost solutions - all with exceptional jitter performance.”

According to market research firm Databeans, the clock generation IC market will grow to approximately $1.25bn in 2018. Microsemi's ZL30244, ZL30245 and ZL30255 are available now.
