What is SerDes?

SerDes (Serializer/Deserializer) is a pair of functional blocks commonly used to convert data between serial and parallel interfaces in high-speed communication systems.

Key Concepts:​

  • Serializer: Converts parallel data to serial
  • Deserializer: Converts serial back to parallel
  • Reduces pin count, simplifies routing
  • Common in PCIe, SATA, JESD204, Ethernet

Applications:​

  • Inter-IC communication
  • Backplanes
  • Optical and copper interfaces
