In Depth
Lowest-power serial connectivity
The RocketIO GTP transceiver design consumes less than 100 mW at 3.75 Gbps, the lowest power in the industry and a 77% reduction compared to Virtex-4 FPGAs.
Ease of design
The RocketIO GTP transceiver wizard simplifies configuration with time-saving, menu-driven configuration for PCIe®, XAUI, OC-48, GE interfaces. The tool produces a wrapper, an example design, and a test bench for rapid integration and verification of the serial interface with your custom function.
A wide range of settings for Tx and Rx equalization enable you to tune transceivers for reliable operation on the toughest channels. Built-in PRBS generators and checkers simplify characterization and debug. You can rapidly zero-in on the right setting to achieve maximum design margin. These functions work with industry-standard text equipment as well as Xilinx IBERT tool which provide low-cost, easy-to-use diagnostic capabilities.
