Applications
Figure 1 is a schematic of the CPC2400E in a typical
host system application. The host system communi-
cates to the CPC2400E through a standard V.24 serial
interface. Refer to the Pinout and Definitions section for
functional descriptions of the pins. The transmit and
receive data is sent over the TXD and RXD pins. The -
DCD and -DTR pins are used for handshaking. The
audio output pin, A1 is used for monitoring the analog
data and can be amplified to drive a speaker. The -
MUTE can be used to enable or disable the speaker.

MODEM
The ferrite beads FB1 and FB2 may be required to
reduce EMI emissions per FCC Part 15. Determining
the value for the ferrite beads depends solely on the
emissions generated by the end user product.
Figure 2 is a schematic of the CPC2400E in a stand-
alone RS232C configuration. This circuit uses the Linear
Technologies LT1181A RS232 line driver. Note that the
LT1181A line driver inverts the signals. Both figures 1
and 2 are for reference purposes only. Exact component
values should be determined by the user.
