Pin Descriptions
PIN NAME
DESCRIPTION
1
/DCD
/DCD is an active low output from the modem. /DCD indicates the presence of a valid carrier
signal.
2
/CTS
/CTS is an active low output from the modem. When hardware flow control is active, the modem
asserts /CTS to indicate that it can accept data from the terminal equipment on /TXD.
3
/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.
4
/DSR
DSR is forced active within the XE5692G module.
5
/RTS
/RTS is an active low input to the modem. When hardware flow control is active, /RTS indicates
to the modem that the host has data to send.
6
/DTR
/DTR is an active low input to the modem. The operation of /DTR is controlled by bit 15 of
register U70 and is normally disabled. When enabled, /DTR indicates the Host is ready to
communicate., and if /DTR is removed while the modem is on-line, the mdoem exits data mode
and enter command mode.
7
/RXD
/RXD provides the path for received data and modem responses to be sent from the modem to
the host terminal equipment.
8
/TXD
/TXD provides the path for transmitted data and modem commands to be passed from the host
terminal equipment to the modem.

/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.
10
Ground
Ground provides the reference voltage for all host interface signals.
11
SPKR
SPKR allows connection of a speaker to monitor modem operations. SPKR cannot directly drive
a speaker. An amplifier with a minimum input impedance of 300 ohms is required. The signal on
SPKR is controlled by the ATM command.

No internal connection
13
/INT
/INT provides an active low hardware interrupt signal from the XE5692G. The operation of this
interrupt pin is programmable using the modem’s register U70.

Tip
The Ring and Tip signals provide modem the connection 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 all public switched
telephone lines. The XE5692G will operate regardless of the polarity of this “Battery” voltage.
The “Battery” voltage drives up to 100 milliamps of DC loop current.
UL60950 requires minimum creepage and clearances distances be maintained between the Tip
and Ring traces and all other circuits. Clearance is the shortest distance between conductive
circuits; creepage is the distance between conductive surfaces along the surface
23
N/C
No internal connection, To prevent damage in case of voltage surges on the telephone line, we
recommend that nothing be connected to this pin.

XE5692G Soldering Instructions
The XE5692G is subject to damage if overexposed to heat during solder reflow operations. Following the soldering
instructions below will ensure that the process of soldering the module to the board does not damage the modem.
The XE5690G must not be exposed to direct Infrared (IR) heating. If your process includes direct IR heating, you
must shield the XE5692G from the infrared rays.

Notes:

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 Novocap LS1808N102K302NX080T. 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.
3. F1 is a positive thermal coefficient (PTC) device which protects the modem from excessive current flow. These
devices are required for your system to pass UL60950. Fuses may be used in place of the PTC’s

Application Note: Using a 68-Pin PLCC Socket
The XE5692G can be inserted into a socket for a 68-pin PLCC device. The HyPLCC package uses only 20 pins; 15
on one side and 5 on the opposite side. Alignment within the socket is critical for all pins of the XE5692G to make
contact with the appropriate pins of the PLCC socket. The drawing below illustrates how the XE5692G fits into the
68-pin PLCC socket. Emulation Technology’s S-SMT-17-068-A socket is representative of sockets that can be used

determines data rate by measuring the width of the
incoming bits. Parity is determined by comparing the
parity bits of the "A" and the "T."
Command Line - Commands may be strung together in a
single command line of up to 48 characters. Commands
are executed in the sequence they appear. Spaces may be
inserted into the command line but do not fill space in the
command buffer. If the command buffer overflows, the
modem issues an "ERROR" result code and commands
are not executed. A carriage return terminates the
command line and causes the commands to be executed.
Register S3 allows the user to select a character other than
a carriage return to terminate the command line.

XE5692G Boot Command
The XE5692G 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 XE5692G 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.
FCC ID Number - pending
US:DWEMM00BXE5692G
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.
