[1] Propagation delays are not relevant for LIN protocol transmission, value only information parameter
[2] No production test, guaranteed by design and qualification
[3] See Figure 2 – Transmit delay
[4] See Figure 7 - Slope time and slew rate calculation in accordance to LIN 1.3
[5] This parameter is tested by applying a square wave signal to the bus. The minimum slew rate for the bus rising and falling
edges is 50V/us
[6] See Figure 3 – Receiver debouncing and propagation delay
[7] In accordance to LIN physical layer specification 1.3
[8] In accordance to LIN physical layer specification 2.0
[9] See Figure 8 - Duty cycle calculation in accordance to LIN 2.0
