SerDes (Serializer/Deserializer) is a critical technology used in high-speed data transmission, enabling efficient communication between integrated circuits (ICs), processors, and communication systems. As industries demand faster data transfer rates, SerDes plays a vital role in applications such as data centers, automotive systems, 5G networks, and high-performance computing (HPC).

What is SerDes?
SerDes is a pair of functional blocks:

Serializer – Converts parallel data into a serial data stream for transmission.

Deserializer – Converts the received serial data back into parallel format for processing.

By reducing the number of physical connections required for high-speed communication, SerDes improves efficiency, signal integrity, and performance while minimizing power consumption.

How SerDes Works
Data Transmission Process
Parallel Data Input – Multiple data bits are received from a processor, FPGA, or memory device.

Serialization – The data is converted into a high-speed serial stream.

Transmission Over a Single Channel – The serialized data travels via copper traces, fiber optics, or high-speed links.

Deserialization – The receiver converts the serial stream back into parallel data.

Parallel Data Output – The deserialized data is delivered to the receiving device for processing.

This process allows high-bandwidth data transfer with reduced wiring complexity.
