Connection Type Description
Used for mode selection on pin 8 (4.7kΩ pull up to V
CC
, 0Ω pull down to GND,
JMP1 4 pin jumper
customer installable pull down for devices with slew rate control R
S
pin).
Connection for access to all critical digital I/O, supply and GND for driving the CAN
JMP2 10 pin header
transceiver externally with test equipment or interfaced to a processor EVM
JMP3 4 pin header CAN bus connection (CANH, CANL) and GND
Connect 120Ω CAN termination to the bus. Used separately for a single termination if
EVM is at end of the CAN bus and termination isn’t in the cable. Used in combination
JMP4 2 pin jumper
with JMP5 to get to second CAN termination to represent the combined 60Ω load for
CAN transceiver parametric measurement.
Connect 120Ω CAN termination to the bus. Used in combination with JMP4 to get to
JMP5 2 pin jumper second CAN termination to represent the combined 60Ω load for CAN transceiver
parametric measurement.
Functional use of pin 5. Options for use are:A) 4.7kΩ pull up to V
CC
for transceiver
with digital input on pin 5B) 0Ω pull down to GND for transceiver with digital input on
pin 5C) Active split termination: for CAN transceiver with V
REF
or SPLIT pin where
JMP6 5 pin jumper
active split termination is desired. Connect to V
CM
and populate the components
R7/R15 and C4 as required for the system.D) V
RXD
(V
IO
) for CAN transceivers with a
separate V
RXD
(V
IO
) for I/O level shifting.
