APPLICATIONS INFORMATION
GENERAL CONSIDERATIONS
Figures 1 and 2 show basic circuit diagrams for
K-Series modem integrated circuits. K-Series products
are 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. Two typical DAA
arrangements are shown: one for a split ±5 or ±12 volt
design and one for a single 5 volt design. These
diagrams are for reference only and do not represent
production-ready modem designs.
K-Series devices are available with two control
interface versions: one for a parallel multiplexed
address/data interface, and one for a serial interface.
The parallel version is intended for use with
8039/48 or 8031/51 microcontrollers from Intel or
many other manufacturers. The serial interface 22-

microcontrollers or in applications where only a
limited number of port lines are available or the
application does not lend itself to a multiplexed
address/data interface. The parallel versions may
also be used in the serial mode, as explained in
the data sheet pin description.

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.
