Using ISERDESE2 (Serdes) in Xilinx FPGA's with Vivado

Описание: In this video, Dr. Paul Kerstetter explains deserialization in FPGAs and walks through the Xilinx ISERDESE2 primitive.

Modern ADCs often send data over high-speed serial links instead of wide parallel buses. This shift helps eliminate trace-length matching issues at high frequencies — but it also means the FPGA must deserialize that fast serial bitstream into parallel data for processing.

That’s where the ISERDESE2 comes in.
In this tutorial, we explore:
✅ Why ADCs use serial interfaces
✅ SDR vs DDR deserialization
✅ How the ISERDESE2 works in Xilinx 7-Series FPGAs
✅ Clock alignment and timing challenges
✅ Practical bring-up tips and common pitfalls
✅ Working design + simulation example

If you're designing with Artix-7, Kintex-7, Virtex-7, or Zynq-7000 FPGAs and working with high-speed data (like 1 Gb/s ADC streams), this video will help you understand how to use the ISERDESE2 for reliable deserialization.
