Low Voltage Differential Signaling
Review routing guidance for LVDS. Numeric differential calculation is temporarily unavailable; confirm pair geometry with a validated field solver and your fabricator.
Common LVDS Applications
| Application | Typical Pairs | Data Rate | Nominal Differential Z |
|---|---|---|---|
| LCD Displays | 4-8 pairs | 100-500 MHz | 100Ω |
| Camera (CSI-2) | 1-4 pairs | Up to 2.5 Gbps/lane | 100Ω |
| SerDes Links | 1-2 pairs | Up to 3.125 Gbps | 100Ω |
| FPD-Link III | 1-4 pairs | Up to 2.975 Gbps | 100Ω |
LVDS PCB Design Guidelines
100Ω Differential
The nominal differential impedance target for LVDS is 100Ω. Check your specific interface specification and SoC/PHY datasheet for the target for variants such as RSDS.
Termination
Check your receiver datasheet for termination requirements, including whether termination is internal or external and where to place external components.
Length Matching
Tolerance and intra-pair / inter-pair skew budgets are defined in the current interface specification and your SoC/PHY datasheet; check them there. This page does not state them.

LVDS Design FAQ
What impedance for LVDS?
The nominal differential impedance target for LVDS is 100Ω. Tolerance and intra-pair / inter-pair skew budgets are defined in the current interface specification and your SoC/PHY datasheet; check them there. This page does not state them. Check your receiver datasheet for termination requirements.
How long can LVDS traces be?
Check the current interface specification and your SoC/PHY datasheet for channel length constraints; this page does not state a trace-length limit.
Do I need external termination?
Check your receiver datasheet for termination requirements, including whether termination is internal or external and where to place external components.
What's the difference between LVDS and SubLVDS?
SubLVDS (SLVS) uses lower voltage swing and is common in camera sensors. It typically uses the same 100Ω impedance but different voltage levels.
