PRODUCTION DATA.
Unless otherwise specified, the characteristic impedance for single-ended interfaces is recommended to be between 35 Ω and 65 Ω to minimize the overshoot or undershoot on far-end loads.
Characteristic impedance for differential interfaces must be routed as differential traces on the same layer. The trace width and spacing must be chosen to yield the recommended differential impedance. For more information see Section 7.5.1.
The PDN must be optimized for low trace resistance and low trace inductance for all high-current power nets from PMIC to the device.
An external interface using a connector must be protected following the IEC61000-4-2 level 4 system ESD.
