Detailed Description
The HIN2XXA family of high-speed RS-232
transmitters/receivers are powered by a single +5V power
supply, feature low power consumption, and meet all ElA
RS232C and V.28 specications. The circuit is divided into
three sections: the charge pump, transmitter, and receiver.
Charge Pump
An equivalent circuit of the charge pump is illustrated in
Figure 3. The charge pump contains two sections: The
voltage doubler and the voltage inverter. Each section is
driven by a two phase, internally generated clock to generate
+10V and -10V. The nominal clock frequency is 125kHz.
During phase one of the clock, capacitor C1 is charged to
VCC . During phase two, the voltage on C1 is added to VCC,
producing a signal across C3 equal to twice VCC. During
phase two, C2 is also charged to 2VCC, and then during
phase one, it is inverted with respect to ground to produce a
signal across C4 equal to -2VCC. The charge pump accepts
input voltages up to 5.5V. The output impedance of the
voltage doubler section (V+) is approximately 200
, and the
output impedance of the voltage inverter section (V-) is
approximately 450
. A typical application uses 0.1F
capacitors for C1-C4, however, the value is not critical.
Increasing the values of C1 and C2 will lower the output
impedance of the voltage doubler and inverter, increasing
the values of the reservoir capacitors, C3 and C4, lowers the
ripple on the V+ and V- supplies.
