(4) Duty cycles: LIN driver bus load conditions (C
LINBUS
, R
LINBUS
): Load1 = 1 nF, 1 kΩ; Load2 = 10 nF, 500 Ω. Duty cycles 3 and 4 are
defined for 10.4-kbps operation. The SN65HVDA195 also meets these lower data rate requirements, while it is capable of the higher
speed 20-kbps operation as specified by Duty cycles 1 and 2. SAEJ2602 derives propagation delay equations from the LIN 2.0 duty
cycle definitions, for details see the SAEJ2602 specification.
