SerialLite III Streaming Intel® FPGA IP

Serial Lite III Streaming

Serial Lite III is a simple, low-latency, scalable protocol for high-bandwidth serial data transfer applications. The Serial Lite III Streaming Intel® FPGA Intellectual Property (IP) core offers simple connectivity that enables rapid point-to-point data transfers across various transmission media, including printed circuit board (PCB), backplane, copper cabling, and fiber optics.

The Serial Lite III Streaming Intel FPGA IP core includes Intel’s technology-leading transceivers:

  • Physical medium attachment (PMA)
  • Physical coding sublayer (PCS)
  • Media access control (MAC) layers 

The PCS and PMA layers are hardened within the Intel® Stratix® 10, Intel® Arria® 10, Stratix® V, and Arria® V FPGAs to save customers valuable FPGA logic resources. 



The hardened PCS/PMA functionality enables much easier timing closure for all types of designs. The Serial Lite III protocol was designed to provide the necessary reliability, low latency, overhead, and scalability to ensure efficient data transfers and maintain low bit error rates required by today’s and next-generation systems.

  • Data rate selection up to 28 Gbps
  • Multi-lane configuration up to 24 lanes
  • Data streaming operations - continuous or bursty
  • Simplex and full duplex operations
  • Flexible user clocking modes
  • Hardened resource utilization advantage
  • Low-latency data transfer (< 150 ns: TX + RX)
  • Minimal transmission overhead
  • 64B/67B encoding/decoding scheme
  • Optional error correction code (ECC) support on M20K's (SEU mitigation)
  • Optional error injection or detection and health monitoring
  • Fully integrated IP (MAC, PCS, and PMA layers)
  • Tunable pre-emphasis and equalization settings
  • Support for both AC and DC coupling
