Module crosstalk 

Standalone crosstalk calculator.

Note: This calculator is marked “Unsupported” in the original Saturn PCB Toolkit due to formula accuracy concerns. Included for completeness.

Estimates backward crosstalk (NEXT) using the standard coupled-line model:

Kb = 1 / (4 × (1 + (S/H)²)) Lsat = rise_time × v_prop / 2 NEXT = Kb × min(coupled_length / Lsat, 1.0)

Known Limitations

The standard Kb formula does not match Saturn’s test vector (-2.23 dB / 3.87 V). Saturn likely uses a different formula or additional correction factors.

TODO

• Match Saturn formula exactly
• Stripline variant
• Forward crosstalk (FEXT) estimation
