Overview
Description
The RXS2448 is a RapidIO®, multi-port switch that is compliant with the Serial RapidIO Interconnect Specification (Revision 3.2). The switch fabric supplies a non-blocking bandwidth of 600Gbps for up to 24 ports and 48 lanes. The packet transfer performance through the fabric is optimized through buffer management schemes and configurable queuing modes. The RapidIO switch supports standard RapidIO routing functionality, including unicast and up to 256 multicast groups.
The RXS2448 supports flow control based on eight separate priorities that contains a queue aging function to ensure that high-priority traffic does not starve low-priority traffic under congestion. The device provides extensive accessibility to create an optimal configuration by allowing access to all features of the switch via any port.

Hi. I'm Trevor Hiatt, and I'm happy to introduce IDT's next generation RapidIO switches, the RXS family. Supporting the latest 10xN RapidIO standard, these chips are extremely low latency and high bandwidth, and are designed to take on the challenges of the coming 5G mobile network, as well as other compute intensive applications. IDT introduced our prior generation of RapidIO switches in 2010, and since then they've become ubiquitous in communications infrastructure, with virtually every 4G phone call and download around the world going through our chips.
They're also being used for mobile edge and high-performance computing and data analytics. That's because RapidIO delivers the ultra-low latency needed to efficiently move and manage vast volumes of data. With our new family of RapidIO switches, ultra-fast just got a whole lot faster. We're talking about port to port latency approaching 100 nanoseconds, and a flexible non-blocking fabric with switching performance of 600 gigabits per second. That's greater than twice the performance of the prior generation, exceeding the bandwidth requirements of the 10xN standard, and all with better energy efficiency than our prior generation and competing solutions.
In addition to being optimized for 5G infrastructure, the 10xN switches are ideal for 4G LTE-Advanced systems, as well as a wide variety of markets where latency creates a bottleneck to achieving the potential performance of a system. These markets include mobile infrastructure, data center, aerospace, industrial control, and defense. The new family is comprised of the RXS2448, with 24 ports and 48 lanes, and the RXS1632 with 16 ports and 32 lanes. They're backward compatible with existing RapidIO ecosystems, protecting previous hardware and software investments. Leveraging this compatibility can accelerate a product's time to market.
There's lots more information about the RXS switches on the IDT website at www.idt.com/go/rapidio. Thanks for watching.
