Differential impedance, jitter, and loss limits
Use one tab at a time. Spacing, height, and length are millimetres. Jitter is picoseconds or nanoseconds. Frequency is megahertz or gigahertz.
Your result
The loss sum is not shown as a result.
c1 multiplies the square root of the frequency number you type. Its dimension is loss divided by that square root. MHz and GHz are labels, not a conversion.
c2 multiplies that frequency number times the dimensionless loss tangent. Its dimension is loss divided by the frequency number.
The equation does not state dB, dB per length, or nepers, and it does not include trace length. This page therefore does not print the numeric sum.
Frequency: 1 GHz

- Edge spacing over heightDifferential impedance uses the spacing-to-height ratio. Length is labeled and not used in that equation.Load these inputs
- Total jitter at BER 1e-12Dj and Rj are picoseconds. The coefficient 14.069 is only for that bit-error rate.Load these inputs
