HOTLink II I/O Boards

Delivers massive data throughput for realtime analysis

HOTLink II I/O Modules from Radiance Technologies leverage the HOTLink IIT protocol to reliably transfer large data streams at rapid rates. Our PMC modules transfer 8-bit parallel data across low-cost copper media at 1500 Mbps-more than three times faster than first-generation HOTLink modules. The low latency of the built-in HOTLink II protocol engine eliminates software overhead related to network protocols. By conserving FPGA resources and adhering strictly to the Cypress Semiconductor's HOTLink II protocol, our PMC modules support additional custom framing and packet protocol layers that simplify development during transmission and reception.
