High Performance Single-In-Line DAA Module

Description

Xecom created the XE0016 for low distortion voice and modem applications. The XE0016 integrates a two-to- four 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;

*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.

NAME

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.
