GENERAL DESCRIPTION
The EVAL-ADM3051EBZ allows quick and easy evaluation of the
ADM3051
CAN transceiver. The evaluation board allows all of
the input and output functions to be exercised without the need
for external components. Screw terminal blocks provide convenient
connections for logic signals and power.
The main device on the evaluation board, the
ADM3051
, is a
controller area network (CAN) physical layer transceiver,
allowing a protocol layer CAN controller to access the physical
layer bus. The
ADM3051
complies with the ISO 11898
standard. It is capable of running at data rates of up to 1 Mbps.
For evaluation with a bus cable, a screw terminal block is
provided to allow connection of CANH and CANL signals and
connection of the cable shield.
The operating mode of the
ADM3051
can be selected by
jumper configuration. Three operating modes are available:
high speed, slope control, and standby. Selecting standby mode
connects Pin 8 (RS) of the
ADM3051
to V
CC
, placing the device
in a low current standby mode. Selecting slope control mode
limits EMI by connecting RS with a 47 kΩ resistor to ground to
modify the rise and fall of slopes. This mode facilitates the use
of unshielded cables. Alternatively, selecting high speed mode
disables slope control by connecting RS to ground, allowing
high speed operation. Shielded cables or other measures to
control EMI are necessary in this mode.
