What Is an HSD Cable?
An HSD (High Speed Data) cable is a highspeed, shielded data cable widely used in automotive and industrial applications. It is designed for transmitting highbandwidth signals such as video, highspeed data, and SerDes/LVDS communications with strong electromagnetic interference (EMI) resistance.
1. Main Purpose
HSD cables are primarily used to carry:
HD video signals (vehicle cameras, surroundview systems)
Highspeed data (infotainment systems)
LVDS / SerDes communication
Radar and sensor data
They are known for high bandwidth, low signal loss, and excellent EMI protection.
2. Typical Cable Structure
HSD cables usually come in quadshielded coaxial or twistedpair shielded designs. A typical structure includes:
Inner conductor: tinned copper or bare copper
Insulation: lowdielectric materials such as PE or FEP
Shielding: aluminum foil + braided shielding (duallayer EMI protection)
Outer jacket: PVC, TPE, or TPU (oilresistant, flameretardant)
This construction ensures stable highspeed transmission even in the complex electromagnetic environment of a vehicle.
3. Key Features
Supports multiGbps data rates
Excellent EMI shielding
Flexible routing for complex automotive harness layouts
Low latency and low signal attenuation
4. Common Applications
| Application | Description |

5. HSD vs. Standard Data Cables
| Comparison | HSD Cable | Standard Cable |
| Data rate | High | Medium/Low |
| EMI resistance | Strong (multilayer shielding) | Limited |
| Signal stability | Signal stability | Moderate |
| Typical use | Automotive, industrial | Consumer electronics |
