Figure 10. Charge Pump Voltage Inverter
T ransmitter (Driver) Section
T he drivers convert 3.3 V logic input levels into RS-232 output
levels. With V
CC
= +3.3 V and driving an RS-232 load, the
output voltage swing is typically
±
6 V.
Receiver Section
T he receivers are inverting level-shifters that accept RS-232
input levels and translate them into 3 V logic output levels.
T he inputs have internal 5 k
pull-down resistors to ground and
are also protected against overvoltages of up to
±
30 V. Uncon-
nected inputs are pulled to 0 V by the internal 5 k
pull-down
resistor. T his, therefore, results in a Logic 1 output level for
unconnected inputs or for inputs connected to GND.
T he receivers have Schmitt trigger inputs with a hysteresis level
of 0.4 V. T his ensures error-free reception for both noisy inputs
and for inputs with slow transition times.
HIGH BAUD RAT E
T he ADM3202E/ADM3222E feature high slew rates permitting
data transmission at rates well in excess of the EIA/RS-232E
specifications. RS-232 voltage levels are maintained at data rates
up to 460 kbps even under worst case loading conditions. T his
allows for high speed data links between two terminals or indeed
it is suitable for the new generation I
SDN
modem standards which
requires data rates of 230 kbps. T he slew rate is internally con-
trolled to less than 30 V/
μ
s in order to minimize EMI interference.
