The Design of LVDS Bus with High EMC Compliance

The article deals with results which were obtained during the design of LVDS (low voltage differential signaling) bus. This bus is very resistant to interference from the environment and to spurious emission of electromagnetic fields. According to requirements we prepared designs of LVDS by means of numerical methods. The design was realized and its parameters verified experimentally. The basic parameter of bus impedance Z = 100 Omega, frequency f
₁
= 100 MHz of the first harmonic of rectangle signal.
