Compact, Low-Cost Global Embedded V.92 Modem
Description
Features
The Xecom XE5692SM provides a complete,
global modem as a compact module. Only Xecom
XE5692SM-1 (Surface-Mount Model)
offers embedded modems in both through-hole and
surface-mount form.
XE5692SM: 2.175” x 1.0” x 0.30”
XE5692SM-1: 2.175” x 1.0” x 0.152”
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 XE5692SM footprint is 20% smaller than the
most popular embedded modems. The surface-

allows the development engineer greater flexibility
in placement of the modem within the host system.
Xecom offers two interchangeable models: the
XE5690SM and XE2422SM, that provide lower
cost, lower speed modem alternatives.

Tip
The Ring and Tip signals connect the modem to the telephone line. FCC Part 68
Rules require a 1500 volt isolation barrier between the telephone line and all other
circuits. This isolation must be preserved throughout the system.
The telephone company places a DC “Battery” voltage across Tip and Ring on public
switched telephone lines. The XE5692SM operates regardless of the polarity of this
voltage. The “Battery” voltage drives up to 100 milliampere of DC loop current.
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

PIN NAME
DESCRIPTION
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.
3
/INT
/INT provides an active low hardware interrupt signal from the XE5692SM. The
operation of this interrupt pin is programmable using the modem’s register U70.
4
/RESET
/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.
5
SPKR
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.
6
Ground
Ground provides the reference voltage for all host interface signals.
7
/RI
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.
8
/DTR
/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.
9
/TXD
/TXD provides the path for transmitted data and modem commands to be passed
from the host controller to the modem.
10
/RXD
/RXD provides the path for received data and modem responses to be sent from the
modem to the host controller.
11
/RTS
/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.
12
/DSR
/DSR is an active low output from the modem and is forced to the active condition.
13
/CTS
/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
equipment on /TXD.
14
/DCD
/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
XE5692SM asserts /DCD.
15
VCC
VCC provides 3.3 volt power to the modem.

Notes:
1 Capacitors, C1 and C2, may be required for EMI filtering in your system. Without these components
you may experience unintended radiation when the telephone cable is attached. C1 and C2 are high-
voltage capacitors. We recommend the Johanson Dielectrics 502S47N102KV6T. This 1000 pfd, 3000
volt capacitor will direct the high frequency harmonics to the system ground. These capacitors must
be rated at a minimum of 1500 volts to maintain the isolation required by FCC Part 68 Rules.

XE5692SM Boot Command
The XE5692SM allows a default command string to be automatically loaded into the modem on power-up or
modem reset. A series of commands loads the default command string in Hex form into the modem’s
EEPROM. The EEPROM has 256 bytes available for command storage.
The sequence to load the default commands into EEPROM must begin with the Boot command and ends
with a double carriage return. All commands are loaded into the EEPROM in Hex form beginning with
address M0000. Up to 8 addresses may be loaded with each command in the sequence.
The following example uses a typical configuration for an embedded application. ATE0 disables
command echo; ATQ1 disabled modem responses, and ATS0=1 sets the modem to automatically answer
on the first ring. This sequence is loaded into the modem EEPROM with the Boot command using the
command sequence below. This places the modem into the desired configuration each time power is
applied or the modem is reset.

FCC Instructions
The XE5692SM complies with Part 68 of the FCC Rules and Regulations. With each device shipped,
there is a label which contains the FCC Registration Number. The FCC Registration number
incorporates the Model Number, Manufacturer Indentifier, Product Type identifier and Ringer
Equivalence Number (REN) for this product. You must, upon request, provide this information to your
telephone company. the format of the FCC Registration Number is shown below.
US: DWEMM00BXE5692SM
The mounting of this device in the final assembly must be made in such a manner as to preserve the high
voltage protection between the TIP/RING Connection and the rest of the system. Typically, this may be
accomplished by maintaining a minimum spacing 100 mils between the TIP/RING Traces to the RJ-11C
Jack and low voltage portion of the system. No additional circuitry may be attached between TIP/RING
and the telephone line connection, unless specifically allowed in the rules.
The REN is useful to determine the quantity of devices you may connect to a telephone line and still have
all of these devices ring when the number is called. In most, but not all areas, the sum of the RENs of all
devices connected to one line should not exceed five (5.0). To be certain of the number of devices you
may connect to the line, as determined by the REN, you should contact the local telephone company to
determine the maximum REN for you calling area.
If your system causes harm to the telephone network, the telephone company may discontinue service
temporarily. If possible, they will notify you in advance. If advance notification is not practical, you will be
notified as soon as possible.
Your telephone company may make changes in its facilities, equipment, operations or procedures that
could affect proper functioning of your equipment. If they do, you will be notified in advance to give you
an opportunity to maintain uninterrupted telephone service.
If you experience trouble with this device, please contact XECOM at (408) 945-6640 for information on
obtaining service or repairs. The telephone company may ask you to disconnect this device from the
network until the problem has been corrected or until you are sure that the device is not malfunctioning.
