TERMINOLOGY

IDD1

IDD1 is the current drawn by the VDD1 pin.

IDD2

IDD2 is the current drawn by the VDD2 pin.

VOD and VID

VOD and VID are the differential voltages from the transmitter or

at the receiver on the CANH and CANL pins.

tTXD_DOM

tTXD_DOM is the propagation delay from a low signal on TXD to

transition the bus to a dominant state.

tTXD_REC

tTXD_REC is the propagation delay from a high signal on TXD to

transition the bus to a recessive state.

tLOOP_FALL

tLOOP_FALL is the propagation delay of a low signal on the TXD pin to

the bus dominant. tLOOP_FALL transitions low on the RXD pin.

tLOOP_RISE

tLOOP_RISE is the propagation delay of a high signal on TXD to the

bus recessive. tLOOP_RISE transitions high on the RXD pin.

tBIT_TXD

tBIT_TXD is the bit time at the TXD pin as transmitted by the CAN

controller. See Figure 2 for level definitions.

tBIT_BUS

tBIT_BUS is the bit time as transmitted by the transceiver to the

bus. When compared with a given tBIT_TXD, a measure of bit

symmetry from the TXD digital isolation channel and CAN

transceiver can be determined. See Figure 2 for level definitions.

tBIT_RXD

tBIT_RXD is the bit time on the RXD output pin, which can be

compared with tBIT_TXD for a round trip measure of pulse width

distortion through the TXD digital isolation channel, the CAN

transceiver, and back through the RXD isolation channel.
