The PHE features four levels of memory, 32 Risc core processors to perform user-programmed In-Memory Functions (IMFs), along with all of the fixed BURST and RMW functions included in the BE3 products. We combine this with our high-speed serial protocol I/O interface to enable your applications to achieve hyperspeed performance.Read more
System designers face a never-ending challenge of increasing system throughput and density. By aggregating two lower speed serial links together with a serial Mux/Demux device, designers can:
- Halve the required number of physical lanes for the same throughput
- Double system throughput with the same number of physical lanes or pins
The below diagram illustrates how pairs of 12.5Gb/s links are combined to form a bidirectional 25Gb/s link. An example application includes multiplexing the 4x10G lanes of a 40GbE link to 2x20G, thus either doubling the density of 40Gb Ethernet ports
or halving the number of signals.
KEY SYSTEM CONSIDERATIONS:
- Supports industry communication standards
- Protocol independent data payloads for datacom, telecom, storage, or other applications
- Strong signal integrity ensuring reliable data transfer
- Support Forward Error Correction (FEC) payloads for high-reliability
- Package and power options supporting line card, daughter card and module applications are key to system integration, power and heat issues
THE MOSYS SOLUTION:
The MoSys MSH420S device is an ideal solution for multiplexing and demultiplexing high-speed serial links.
- Two serial links transported across a single faster (2x) serial link provides:
- Half the required number of physical lanes for the same payload
- Double the payload for same number of physical lanes
- Up to 5, Bi-directional, Mux/Demux channels in a single MSH420 device
- Or up to 2 channels in a single, smaller MSH422S device (contact factory)
- Supports critical industry standards, such as:
- IEEE and OIF 10G, 25G, 40G and 100G standards
- Protocol independent payload supports Datacom, Telecom, Storage applications
- Independent PLLs per lane support different data rates per Mux/Demux channel within a single device
- Signal integrity is key to ensuring reliable transfer of data
- MoSys self-adapting RX equalizers for ease of connection
- Reduce board design and bring-up time by eliminating per-lane “tuning”
- Cost/performance must be considered in any system design:
- Some devices are available in volume at less than $50 each
KEY POINTS SUMMARY:
- Mux/Demux of serial links can double the throughput or halve the number signals in your system design.
- Adherence to industry standards for interoperability with other available industry devices
- Strong signal integrity and package/power options support cable, backplane, printed circuit boards and module level solutions.
