Serializers/Deserializers (SerDes) are semiconductor devices that convert parallel data streams into serial formats (Serializer) and vice versa (Deserializer). These ICs enable high-speed data transmission in modern electronic systems by reducing physical signal lines while maintaining data integrity. SerDes technology is fundamental to high-bandwidth communication protocols in computing, automotive, and industrial applications.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Point-to-Point SerDes | Dedicated link between two devices, low latency | PCIe interconnects, GPU memory interfaces |
| Embedded Clock SerDes | Integrated clock recovery, reduced signal lines | DisplayPort, HDMI 2.0+ interfaces |
| Multi-Channel SerDes | Parallel channel bonding for higher throughput | 100G Ethernet optical modules |
