4. Functional Description

GTS Serial Lite IV Intel® FPGA IP consists of MAC and Ethernet PCS. The MAC communicates with the custom PCS through MII interfaces.

The IP supports modulation mode:
  • NRZ—Provides up to 4 lane for selection.
Each modulation mode supports two data modes:
  • Basic mode—This is a pure streaming mode where data is sent without the start-of-packet, empty cycle, and end-of-packet to increase bandwidth. The IP takes the first valid data as the start of a burst.

  • Full mode—This is the packet mode data transfer. In this mode, the IP sends a burst and a sync cycle at the start and the end of a packet as delimiters.
