CAN FD transceiver

The voltages are referred to GND and currents are assumed positive, when the current flows into the pin.

6 V ≤ VSREG ≤ 18 V; 4.8 V ≤ Vcansup ≤ 5.2 V; Tjunction = from -40 °C to 150 °C, unless otherwise specified.

-12 V ≤ (CANH + CANL)/2 ≤ 12 V

normal mode

Active mode: RL = 50 Ω…65 Ω

70% VRXDC (rising) - 30% VRXDC (falling)

CRXD = 15 pF

TXD rise and fall time = 10 ns (10% - 90%, 90%

- 10%)

Test signal to be applied on the TXD input of

the implementation is a square wave signal with

a positive duty cycle of 1/6 and a period of six

times the nominal recessive bit width
