Protecting LVDS Interfaces

Basic LVDS circuit operation
Low-Voltage Differential Signaling or LVDS is a technology used in a variety of high-speed data transmission applications such as switches, set-top boxes and flat panel displays. In the simplest form, an LVDS interface, as defined by IEEE 1596.3 and ANSI/TIA/EIA-644, is a driver that transmits the signal over a trace or a cable to a receiver.
If not protected properly, electrostatic discharge can damage the driver and receiver. In addition, the typical data transmission rate of LVDS is typically 500Mbps up to a theoretical maximum of 1.9Gbps. High data transmission rate applications require protection devices that can provide adequate protection while maintaining signal integrity.

This Whitepaper discusses how to Protect LVDS Interfaces using Protek Devices SRV05-4LC TVS Devices.
