Transmitter Outputs when
Exiting Shutdown
Figure 5 shows a transmitter output when exiting shut-
down mode. The transmitter is loaded with 3k
in par-
allel with 1000pF. The transmitter output displays no
ringing or undesirable transients as it comes out of
shutdown, and is enabled only when the magnitude of
V- exceeds approximately -3V.
High Data Rates
The MAX3228/MAX3229 maintain the RS-232 ±5.0V
minimum transmitter output voltage even at high data
rates. Figure 6 shows a transmitter loopback test cir-
cuit. Figure 7 shows a loopback test result at 120kbps,
and Figure 8 shows the same test at 250kbps. For
Figure 7, the transmitter was driven at 120kbps into an
RS-232 load in parallel with 1000pF. For Figure 8, a sin-
gle transmitter was driven at 250kbps, and loaded with
an RS-232 receiver in parallel with 1000pF.
