APPLICATIONS INFORMATION
GENERAL CONSIDERATIONS
Figure 5 shows the basic circuit diagram for a
73K222BL modem integrated circuit designed to be
used in conjunction with a control processor, a
UART or RS-232 serial data interface, and a DAA
phone line interface to function as a typical
intelligent modem. The K-Series ICs interface
directly with Intel 8048 and 80C51 microprocessors
for control and status monitoring purposes.
A typical DAA arrangement is shown in Figure 5.This
diagram is for reference only and does not represent
a production-ready modem design.
In most applications the controller will monitor the
serial data for commands from the DTE and the
received data for break signals from the far end
modem. In this way, commands to the modem are
sent over the same line as the transmitted data. In
other applications the RS-232 interface handshake
lines are used for modem control.
