APPLICATIONS INFORMATION
GENERAL CONSIDERATIONS
Figures 1 and 2 show basic circuit diagrams for
K-Series
modem
integrated
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.
circuits.
K-Series
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
can be used with other 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.
