______________________________________________________________________________________
Additionally, a current-limiting circuit protects the trans-
mitter output stage against a short circuit to positive
and negative battery voltage. Although the power dissi-
pation increases during this fault condition, this feature
prevents destruction of the transmitter output stage.
Applications Information
Reduced EMI and Reflections
In slope control mode, the CANH, CANL outputs are
slew-rate limited, minimizing EMI and reducing reflec-
tions caused by improperly terminated cables. In gen-
eral, a transmitter
’
s rise time relates directly to the
length of an unterminated stub, which can be driven
with only minor waveform reflections. The following
equation expresses this relationship conservatively:
Length = t
RISE
/ (10 x 1.5ns/ft)
where t
RISE
is the transmitter
’
s rise time. See Figures 5,
6, and 7 for typical waveforms at various data rates.
The MAX3053 requires no special layout considerations
beyond common practices. Bypass V
CC
to GND with a
1μF ceramic capacitor mounted close to the IC with
short lead lengths and wide trace widths.
