lvds_ch6Chapter 6 Cable, connectors, and performance testing 6.1 General comments When choosing cables and connectors for LVDS it is important to remember: 1. Use controlled impedance media. The cables and connectors you use should have a differential impedance of about 100. They should not introduce major impedance discontinuities that cause signal reflections. 2. Balanced cables (twisted pair) are usually better than unbalanced cables (ribbon cable, multi-conductor) for noise reduction and signal quality. Balanced cables tend to generate less EMI due to field canceling effects and also tend to pick up electromagnetic radiation as common-mode (not differential-mode) noise, which is rejected by the receiver. 3. For cable distances
