ZTE Selects IDT's 50Gbit/s RapidIO chips for next generation wireless basestation designs

By Nick Flaherty

Chinese telecoms equipment maker ZTE is to use the new RapidIO 10xN interconnect chips from IDT for its new generation of wireless base stations. The IDT chips, members of the recently introduced RXS switch family, will enable the ZTE systems to evolve and meet the ever-growing need for greater capacity and scalability over the coming years.

IDT's prior generation RapidIO switches are used in virtually every 4G LTE phone call and download made today.

"The data being pushed and pulled over networks is growing at an extraordinary rate, so when we were building our latest wireless base stations, we were careful to select components that can grow and meet future demands," said Tian Sen, chief engineer of ZTE's Baseband Unit Department. "IDT RapidIO switches are ubiquitous in the communications field, and this new generation of switches delivers significantly better performance, preparing us well for the systems of tomorrow."

The 50Gbps RapidIO interconnect enables efficient communication with deterministic latency for use in LTE, next generation LTE-A and 5G systems. These system architectures require communication between many heterogeneous processing components, including ASICs, FPGAs, and processors connected through a RapidIO fabric.

IDT's RXS switches exceed the latest RapidIO 10xN specification and deliver more than twice the performance of IDT's previous generation of switches. In addition to 4G LTE-A and 5G, the RXS switches are ideal for applications with intensive bandwidth and low latency requirements, such as mobile edge computing, high-performance computing, and data analytics.

"More than ever, our network customers are requiring low latency and greater scalability and capacity for their systems," saidRon Jew, general manager in IDT's Computing and Communications Division. "The new RapidIO RXS switches can play a significant role in helping ZTE maintain its leadership position in wireless infrastructure."
