The world’s first and only small-scale PCIe 5.0 ready switch, Zetti, utilizes unique, high-end features, including Peer to Peer transaction and Hot Plug support, and is fully backwards compatible.

Zetti supports one upstream port (up to four lanes) and up to six downstream ports (four or six lanes total), each simultaneously functioning as an independent PCIe port with different speeds and capabilities. This provides maximum system design flexibility - allowing ultra-mobile processors with limited PCIe IO resources to support more PCIe endpoint devices.

“System designers working with lower-cost CPUs in the peripherals and IoT market, with limited die space for PCIe lanes, are currently restricted to 3.0 speeds,” explains Kandou VP of Sales & Business Development, Thomas Boudrot. “If one or more endpoint needs to run at full PCIe 5.0 speed, designers are forced to add more lanes at

a higher cost or employ inefficient workarounds such as under-utilizing bandwidth. This is a waste of time, money, and technology. Zetti offers a solution.”

Kandou VP of Strategy, Subhash Roy, adds: “Picture a busy, multi-lane highway with vehicles coming and going at different speeds and in different directions. The switch is your traffic manager, ensuring everything flows at the speed it needs to, along the right lanes, and in the most optimum way. But not all switches were created equally. Zetti brings high-end features, unique at this small scale, to everyday applications in IoT, medical, mobile computing, industrial PCs, and telecoms markets, for next generation performance.”

About Zetti

A 7-port (8-lane) packet switch, Zetti is PCIe 5.0 ready and fully backwards compatible with PCIe 1.0 to 4.0 technologies. Designed specifically for small form factor and lower power system design with its compact 5.5mm x 10mm package housing, its premium features are unique at this scale. Peer to Peer Transaction offloads CPU memory access workload to reduce latency and power consumption while enhancing performance, while Hot Plug Support - a feature usually only included with large scale switches - comes as standard. Kandou’s advanced on-chip diagnostics tool, Besso, is also built in and included for free for rapid debugging on the bench or in the field to accelerate time to market. Zetti also has support for secure boot platform to prevent cyber attackers from altering its sideband boot configuration stored in external secure SPI flash, and its plug and play design ensures easy integration into systems with global technical assistance and an outstanding lab service from Kandou’s dedicated team.
