Propagation delays are not relevant for LIN protocol transmission, value only information parameter. 8. No production test, guaranteed by design and qualification. 9. See Figure 2 − Input/Output Timing. 10.See Figure 8 − Slope Time Calculation. 11. See Figure 3 − Receiver Debouncing. 12.In accordance to LIN physical layer specification 1.3. 13.In accordance to LIN physical layer specification 2.0. 14.This parameter is tested by applying a square wave to the bus. The minimum slew rate for the bus rising and falling edges is 50 V/ms. |
