Figure 13. Recommended Non-Isolated Active Receiver with HCPL-4100 Isolated Transmitter for Simplex Point to Point 20 mA Current Loop.
25% distortion data rate at different V
tion data rate is defined as that rate at which 25% distortion
occurs to output bit interval with respect to the input bit
interval. Maximum data rate (dotted line) is restricted by
device character is tics. An input Non-Return-to-Zero (NRZ)
test waveform of 16 bits (0000001011111101) was used
for data rate distortion measure ments. Enhanced speed
performance of the loop system can be obtained with lower
V
when loop current is supplied through a resistor instead
of by a current source, an additional series termination
resistance equal to the characteristic line impedance can
be used at the HCPL-4100 transmitter end to enhance
speed of response by approximately 20%.

The cable used contained five pairs of unshielded, twisted,
22 AWG wire (Dearborn #862205). Loop current is 20 mA
nominal. Input and output logic supply voltages are 5 V
dc.
Full Duplex
The full duplex point-to-point communication of Fig-
ure 16 uses a four wire system to provide simultane-
ous, bidirectional data communication between local
and remote equipment. The basic application uses
two simplex point-to-point loops which have two
separate, active, non-isolated units at one common
end of the loops. The other end of each loop is isolated.
