Tejas Networks selects Zarlink ClockCenter products for multiservice switches for optical network expansion
MAY 12, 2010 -- Tejas Networks has designed ClockCenter universal clock translator products from Zarlink Semiconductor into multiservice switch platforms targeting optical transport network (OTN) expansion.
Tejas Networks’ carrier-grade communications equipment are used in telecom networks in India and more than 50 countries around the world.
"Equipment manufacturers need timing solutions that can accept and generate the full range of frequencies required as carriers deploy OTN to cost-effectively deliver all communication services over a single network,” says Louise Gaulin, Product Line Director of Zarlink's Timing and Synchronization group. Zarlink's ClockCenter products offer any rate, any port, all the time performance as single-chip tools to help reduce design time and speed time to market for OTN equipment manufacturers, she adds.
OTN is a next-generation, industry-standard protocol that provides an efficient way to deliver the full range of communication services, including video, data, and multimedia applications, over a single optical network. Zarlink's ClockCenter products are designed to solve the complex synchronization challenges of delivering multiple communication services over optical networks, while delivering design advantages for equipment manufacturers.
"Carriers are aggressively migrating to a scalable, more efficient optical infrastructure to support bandwidth-hungry consumer and enterprise communication applications, including data-intense smartphone and triple play services," says Milind Kulkarni, vice president of engineering with Tejas Networks. "This network evolution requires more intelligent network equipment, such as multiservice switch platforms."
Zarlink's ClockCenter universal clock translator products integrate independent narrow-band digital phase locked loops (PLLs) and a two-stage architecture that supports any rate to any rate frequency translation between up to four input references and up to 20 programmable output clocks.
A single-chip ClockCenter product accepts and generates any frequency (1 kHz to 720 MHz) required to support all communication services delivered over optical and Ethernet networks. As a result, equipment designers can replace multiple components with a single chip to help simplify design and reduce component count and power.
Zarlink's ClockCenter multi-channel synchronous clock translator products are now available.
