June 2005
Compact, Low-Cost Global Embedded Modem
Description
The Xecom XE5690SM provides a complete,
global modem as a compact module. Only Xecom
offers embedded modems in both through-hole and
surface-mount form.
User transferable FCC Part 68 registration comes
with every Xecom modem. This allows the system
designer to add a modem to a process control,
remote monitoring, point-of-sale, or remote
diagnostic system without Part 68 certification.
The XE5690SM footprint is 20% smaller than the
most popular embedded modems. The surface-
mount version frees additional space on the bottom
of the application board. The space efficient design
allows the development engineer greater flexibility
in placement of the modem within the host system.
Xecom offers two interchangeable models: The
XE2422SM offers low speed connectivity at low
cost; the XE5692SM permits fast V.92
connections.

UL60950 requires minimum creepage and clearances distances between the Tip and
Ring and all other circuits. Clearance is the shortest distance between conductive
circuits; creepage is the distance between conductive points along the surface.
/INT provides an active low hardware interrupt signal from the XE5690SM. The
operation of this interrupt pin is programmable using the modem’s register U70.
/RESET is an active low input which initiates a modem hardware reset. /RESET
must be active for a minimum of 100 milliseconds for a proper modem reset
sequence. No external reset is required; if none is used the RESET signal should be
left open.
SPKR provides a Pulse Width Modulated version of the signal on Tip and Ring
allowing connection of a speaker to the modem to monitor modem operations. The
recommended speaker circuit is shown on Page 9 of this data sheet. The signal on
SPKR is controlled by the ATL and ATM commands.
Ground provides the reference voltage for all host interface signals.
The /RI signal reports on the presence of an incoming ring signal. When a ring occurs
across Tip and Ring, the /RI output goes low and toggles with the cadence of the ring
signal.
/DTR is an active low input to the modem. An active /DTR signals the terminal is
available for communications. The AT&D command determines how the modem
interprets activity on /DTR.
/TXD provides the path for transmitted data and modem commands to be passed
from the host controller to the modem.
/RXD provides the path for received data and modem responses to be sent from the
modem to the host controller.
/RTS is an active low input to the modem. When hardware flow control is set, an
active /RTS indicates to the modem that the host has data to send.
/DSR is an active low output from the modem and is forced to the active condition.
/CTS is an active low output from the modem. When hardware flow control is set,
the modem asserts /CTS to indicate that it can accept data from the terminal equip-
ment on /TXD.
/DCD is an active low output from the modem. An active /DCD indicates the
presence of a valid carrier signal. The AT&C command controls when the
XE5690SM asserts /DCD.
VCC provides 3.3 volt power to the modem.
