IFX1051LE functional description preliminary preliminary data sheet 8 rev. 0.92, 2015-07-28 p r e li m i n a r y - s u b je c t t o c h a n g e the ifx1051 is a high-speed can transceiver, operati ng as an interface between the can controller and the physical bus medium. a hs can network is a two wire, differential bus network which allows data transmission rates for can fd frames up to 2 mbit/s. main characte ristics for hs can networks are the two signal states on the hs can bus: ?dominant? and ?recessive? (see figure 3 ). v cc , v io and gnd are the supply pins for the ifx1051. the pins canh and canl are the interface to the hs can bus and operate in both directions, as an input and as an output. rxd and txd pins are the interface to the can controller, the txd pin is an input pin and the rxd pin is an output pin. the rm pin is the input pin for the mode selection (see figure 4 ). by setting the txd input pin to logical ?low? the transmit ter of the ifx1051 drives a ?dominant? signal to the canh and canl pins. setting txd input to logical ?high? turns off the transmitter and the output voltage on canh and canl discharges towards the ?recessive? level. the ?reces sive? output voltage is provided by the bus biasing (see figure 1 ). the output of the transmitter is considered to be ?dominant?, when the voltage difference between canh and canl is at least higher than 1.5 v ( v diff = v canh - v canl ). parallel to the transmitter the normal-mode receiver monito rs the signal on the canh and canl pins and indicates it on the rxd output pin. a ?dominant? signal on the ca nh and canl pins sets the rxd output pin to logical ?low?, vice versa a ?recessive? signal sets the rxd output to logical ?high?. the normal-mode receiver considers a voltage difference ( v diff ) between canh and canl above 0.9 v as ?dominant? and below 0.5 v as ?recessive?. to be conform with hs can features, like the bit to bit arbi tration, the signal on the rxd output has to follow the signal on the txd input within a defined loop delay t loop 255 ns. the thresholds of the digital inputs (txd and rm) and also the rxd output voltage are adapted to the digital power supply v io .
