Applications Information
Reduced EMI and Reflections
In slope-control mode, the CANH and CANL outputs
are slew-rate limited, minimizing EMI and reducing
reflections caused by improperly terminated cables. In
general, 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 = tRISE / (15ns/ft)
where tRISE is the transmitter’s rise time.
The MAX3050 and MAX3057 require no special layout
considerations beyond common practices. Bypass VCC
to GND with a 0.1F ceramic capacitor mounted close
to the IC with short lead lengths and wide trace widths.
