Direct Access Arrangement for Telephone Line Interface
Figure 42 illustrates a 5 V only transmit/receive telephone line
interface for 600
W
transmission systems. It allows full duplex
transmission of signals on a transformer coupled 600
W
line in a
differential manner. Amplifier A1 provides gain that can be
adjusted to meet the modem output drive requirements. Both
A1 and A2 are configured to apply the largest possible signal on
a single supply to the transformer. Because of the high output
current drive and low dropout voltage of the AD8531/AD8532/
AD8534s, the largest signal available on a single 5 V supply is
approximately 4.5 V p-p into a 600
W
transmission system.
Amplifier A3 is configured as a difference amplifier for two
reasons: (1) It prevents the transmit signal from interfering with
the receive signal and (2) it extracts the receive signal from the
transmission line for amplification by A4. A4’s gain can be
adjusted in the same manner as A1’s to meet the modem’s input
signal requirements. Standard resistor values permit the use of
SIP (Single In-line Package) format resistor arrays.
