TCAN1046V Evaluation Module
1 Introduction
1.1 Overview
TI offers a broad portfolio of high speed (HS) CAN transceivers compatible with the ISO11898-2 high
speed CAN standards. These include 5-V V
CC
only, 3.3-V V
CC
only, 5-V V
CC
with I/O level shifting and
galvanic-isolated CAN transceivers. These CAN transceiver families include product mixes with varying
features such as low-power standby modes with and without wake up, silent modes, loop back, and
diagnostic modes.
The TCAN1046V EVM helps designers evaluate the operation and performance of TCAN1046V
transceiver in the SOIC package. It also provides bus termination, bus filtering, and protection concepts. It
is easily configured by the customer to test different configurations with jumper settings, simple soldering
tasks, and replacement of standard components, as well as both CAN interfaces on the device separately.
1.2 CAN EVM
The TCAN1046V EVM has simple connections to all necessary pins of the CAN transceiver device, and
jumpers where necessary to provide flexibility for device pin and CAN bus configuration. There are test
points (loops) for all main points where probing is necessary for evaluation such as GND, V
CC
, TXD, RXD,
CANH, CANL, STBY, and VIO. The EVM supports many options for CAN bus configuration. It is pre-
configured with two 120-
Ω resistors that are connected on the bus via jumpers: a single resistor is used
with the EVM as a terminated line end (CAN is defined for 120-
Ω
impedance twisted pair cable) or both
resistors in parallel for electrical measurements representing the 60- Ω load the transceiver “sees” in a
properly terminated network (that is, 120-
Ω
termination resistors at both ends of the cable). The bus also
has termination of two 60- Ω resistors in series with a 4.7nF capacitor to GND at the midpoint, all soldered
down. This gives the option to test the other typical termination network on CAN buses.
