XE0016

9/99

High Performance Single-In-Line DAA Module

Description

Xecom created the XE0016 for low distortion voice and
modem applications. The XE0016 integrates a two-to­four wire convertor and high performance DAA into a
compact single-in-line module.

The XE0016 integrates a two-to-four wire convertor,
Caller ID circuit, ring detection, loop current holding
circuit, solid-state hookswitch and telephone line
transformer into a compact single-in-line module. The
Caller ID circuit allows the Caller ID signal to pass
through the XE0016. It also permits monitoring of
other signals on the line without seizing the line. The
integral two-to-four wire convertor separates the
transmit and receive signals and is essential for full
duplex communications.

Features

* Small Size: 2.0” long by 0.4” wide by 0.53” high;
* FCC Part 68 Compliant;
* Integrated Low-Distortion Telephone Line

Transfomer supports 33,600 BPS data transfer;

* Provides a signal path for monitoring Caller ID or

other signals on the telephone line without seizing

the line;
* Includes two-to-four wire convertor;
* Passes network signaling tones as large as 0 dBm

without distortion;
* Integral Ring Detection
* Provides 1500 volts isolaton between the telephone

line and all other circuits.
* Integral solid-state hookswitch

XE0016 PIN DESCRIPTIONS

PIN NAME I/O DESCRIPTION

1 Ring --- Ring is one of two signals which form the telephone network connection (RJ11

Pin 4). The XE0016 is not sensitive to the polarity of the battery voltage on the
telephone line. Ring provides 1500 Volts of isolation between the telephone
line and all other circuitry.

2 Tip --- Tip provides the second connection to the telephone network (RJ11 Pin 3). Tip

also provides 1500 Volts of isolation betwen the telephone line and all other
circuits. Xecom rcommends that a minimum distance of .1 inches be
maintained between the Tip and Ring Traces and all other circuits to mainatain
the isolation barrier throughout the system.

3 OH I OH provides active high Hookswitch control. A High on OH closes the internal

relay to connect the equipment to the phone line.

4 TX I TX is the Analog input signal to the XE0016. The input impedance on TX is

typically 10 Kohms at 1800 Hz. The gain or loss of signals placed on TX shall be
no more than 1 dB. Signals on TX are referenced to ground.

5 GND --- Ground reference for the XE0016;

6 Vcc --- Vcc provides +5 Volt power to the XE0016.

7 RX O RX is the Analog output signal from the XE0016. The output impedance of RX is

typically 10 ohms at 1800 hz. The signal level on RX will be within 1 dBm of the
received signal level present on the telephone line. Signals on RX are
referenced to ground.

8 \RI O Ring Indicate, output, active low, TTL, RI provides a half-wave representation of

the Ring as it appears on the telephone line. The /RI output is referenced to
ground.

9 Vdd --- Vdd provides -5 Volt power to the XE0016.
