Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Differential swing (mV)

Required number input.

Check whether an LVDS differential swing in millivolts falls within the 247 mV to 454 mV specification window. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Within specification

The resulting within specification returned as a boolean.

• Signal-integrity estimates depend on edge rate, channel loss, impedance discontinuities, termination, encoding, equalization, clock recovery, jitter decomposition, crosstalk, connectors, vias, and receiver masks. Aggregate budgets must use compatible statistical or worst-case conventions.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Voltage Rating Check

  Check whether the voltage applied across a resistor is within its maximum working voltage rating, which defaults to 250 volts.

• Sense Voltage

  Compute the differential voltage developed across a current-sense shunt as Vsense(mV) = I(A) x Rshunt(mOhm).

• LVDS Termination Power

  Calculate differential termination resistor dissipation as Vdiff,RMS²/R. Use the RMS voltage across the resistor, not transmitter supply voltage.
