FAQs
1. What is the difference between LVDS and EDP cables?
EDP (Embedded DisplayPort) is a digital interface, offering higher bandwidth and simpler connections than analog LVDS. LVDS uses differential signaling, making it more robust against noise.
2. How far can a LVDS cable transmit data effectively?
Effective transmission distance depends on the cable type and data rate. High-speed LVDS cables with proper shielding may transmit data over considerable distances. Signal degradation increases with distance.
3. What are the common connector types for LVDS cables?
Common connector types include I-PEX, Hirose, and Molex. The choice depends on the application’s specific needs regarding size, durability, and pin count.
4. Are LVDS cables susceptible to electromagnetic interference (EMI)?
While LVDS inherently minimizes EMI, unshielded cables remain susceptible. Shielded cables offer better protection against external electromagnetic fields.
5. Can I use an LVDS cable designed for a different application in my system?
It’s generally not recommended. Mismatched cables may lead to signal degradation, data loss, or system malfunction. Using a compatible cable ensures optimal performance.
