Application Guide
LVDS (Low Voltage Differential Signaling)
Considerations:
● LVDS is a low noise, low-voltage signal scheme that uses a small current (typically 3.5mA) to generate a voltage drop across a 100Ω resistor to convey information or data
→ Data rates can vary per application but the ANSI/TIA/EIA-644-A standard recommends a maximum of 655Mbps.
● The medium/high speed bus requires a low capacitance device in 1-6pF range (typically)
→ LVDS schemes will vary in terms of the total number of channels used
→ Protection of 8 data lines is shown below (i.e. CLK+/CLK- and Ax+/Ax-)
