Pin Descriptions

PIN NAME

DESCRIPTION

/DCD

/DCD is an active low output from the modem. It can be used to indicate the presence of a

valid carrier signal. The AT&C command controls when the XE5620G asserts /DCD.

/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.

/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.

/DSR

/DSR is an active low output from the modem. /DSR can be used to indicate that the modem

link is established. The AT&S command controls when the XE5620G asserts /DSR.

/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.

/DTR

/DTR is an active low input to the modem. /DTR can be used to indicate that the terminal is

availble for communications. The AT&D command determines how the modem will interpret

activity on /DTR.

/RXD

/RXD provides the path for received data and modem responses to be sent from the modem to

the host terminal equipment.

PIN NAME

DESCRIPTION

/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..

Ground

Ground provides the reference voltage for all host interface signals.

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 ATL and ATM commands.

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 acrossTip and Ring on all public switched

telephone lines. The XE5620G 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

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.

XE5620G Soldering Instructions

The XE5620G is subject to damage if over-exposed 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 XE5620G must not be exposed to direct Infrared (IR) heating. If your process includes direct

IR heating, you must shield the XE5620G from the infrared rays.

Notes:

C1 and C2 are high-voltage capacitors which may be required for EMI filtering in your system. Without these

components you may experience unintended radiation when the telephone cable is attached to your system. We

recommend selecting components such as the Panasonic ECKDRS471. This 470 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.

2. F1 and F2 are positive thermal coefficient (PTC) devices which protect the modem form excessive current flow.

These devices are required for your system to pass UL60950. Fuses may be used in place of the PTC’s

3. The XE5620G includes internal circuitry to protect the modem from damage due to lightning strikes. However,

any components placed on the Tip and Ring traces will not be protected. If you add any components between

the phone jack and modem module, a surge protector such as the Teccor P3100BA Sidactor should be placed

before these components to protect them from lightning damage.

Application Note: Using a 68-Pin PLCC Socket

The XE5620G 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 XE5620G to

make contact with the appropriate pins of the PLCC socket. The drawing below illustrates how the XE5620G can

be inserted into the 68-pin PLCC socket. Emulation Technology’s S-SMT-17-068-A socket is representative of

sockets that can be sued with the XE5620G.

FCC Instructions

The XE5620G complies with part 68 of the FCC Rules and Regulations. With each device shipped, there is a label which contains,

among other information, the FCC Registration Number and Ringer Equivalence Number (REN) for this product. You must, upon

request, provide this information to your telephone company.

The mounting of this device in the final assembly must be made in such a manner as to preserve the high voltage protection be-

tween 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 cir-

cuitry 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 func-

tioning of your equipment. If they do, you will be notified in advance to give you an opportunity to maintain uninterrupted tele-

phone 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.

The device may not be used on coin service lines provided by the telephone company (this does not apply to private coin tele-

phone applications which use standard telephone lines). Connection to party lines is subject to state tariffs.
