components with large amplitudes are evident. Figure
15 shows the same signal displayed for a MAX3083/
MAX3084/MAX3085, and MAX3089 with SRL = VCC),
transmitting under the same conditions. Figure 15’s
high-frequency harmonic components are much lower
in amplitude, compared with Figure 14’s, and the poten-
tial for EMI is significantly reduced. Figure 16
shows the same signal displayed for a MAX3080/
MAX3081/MAX3082, and MAX3089 with SRL = uncon-
nected, transmitting under the same conditions. Figure
16’s high-frequency harmonic components are even
lower.
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 / (10 x 1.5ns/ft)
where tRISE is the transmitter’s rise time.
For example, the MAX3080’s rise time is typically
1320ns, which results in excellent waveforms with a stub
length up to 90 feet. A system can work well with longer
unterminated stubs, even with severe reflections, if the
waveform settles out before the UART samples them.
