High Data Rates
The ICL32XX maintain the RS-232
output voltages even at high data rates. Figure 7 details a
transmitter loopback test circuit, and Figure 8 illustrates the
loopback test result at 120kbps. For this test, all transmitters
were simultaneously driving RS-232 loads in parallel with
1000pF, at 120kbps. Figure 9 shows the loopback results for
a single transmitter driving 1000pF and an RS-232 load at
250kbps. The static transmitters were also loaded with an
RS-232 receiver.
