Description

Xecom's XE1000 provides a single hardware plat­form for telecom products world-wide. You no
longer need a unique design to comply with the
PTT requirements of each country. The XE1000
provides 4000 volts isolation and, in conjunction
with some external straps or components, meets
the requirements of PTT's throughout the world.

Small size and low power drain make the XE1000
ideal for compact, power-limited applications. The
XE1000 covers just 1.3 square inches of board
space and consume just 2 milliamps from the
single +5 volt supply. The XE1000 includes ring
detect circuitry , off hook control and bell tinkle
suppression for use in the UK.

Features

• Meet World-Wide PTT requirements
(external components may be required)

• 4000 Volts RMS isolation

• BABT Certified

• Small Size (1.05" x 1.25" x 0.40")

• Low Power (typical on-line; 10 milliWatts)

• PSTN and PBX Compatible

• Ring Detection

• Hookswitch Control

• Bell Tinkle Suppression Control (XE1000)

• FCC Part 68 Compliant

XE1000 Pin Configuration & Descriptions

1 /LS Active low, "Line Short" is used

during pulse dialing to short the
line for Tinkle Suppression in the
UK. This line must be held to at
least 4.0 volts to disable the Line
Short.

2 Vcc Vcc is the +5 volt supply voltage

input.

3 /RI This active low, open collector

output provides a pulse train at
twice the ring frequency present
on tip and ring.

4-6 — No Pin

7 T1 The positive input/output for differential analog signals.
8 OH Active low, the on-hook signal places the XE1000 in the on line state. It is pulsed in

combination with LS to provide pulse dialing.

9 GND Ground reference voltage for all control signals.
10 T2 The negative diff erential input/output for analog signals.
11 — No Pin
12 R1 R1 provides the Tip connection to the ring detect circuitry.
13 R2 R1 provides the Ring connection to the ring detect circuitry.
14 RET1 RET1 provides a 600 ohm line match when tied to Pin 17, RET3.
15 RET2 RET2 provides a custom line impedance match when connected to Pin 17, RET3, via

an external RC network.

16 WG1 Normally this pin is tied to Pin 20 but provides a connection for the billing tone filter

when required for homologation.
17 RET3 This pin is used in conjunction with pin 14 or 15 to provide matching line impedance.
18 D1 Normally this pin is tied to Pin 19, Ring, but provides a connection for the billing tone

filter when required for homologation.
19 Ring This Ring signal pro vides one of the two wires f or connection to the telephone network.
20 D2 Normally this pin is tied to Pin 16 but provides a connection for the billing tone filter

when required for homologation.
21 BS This wire provides the bell shunt connection for the UK, blue wire.
22 Tip The Tip signal provides half of the two-wire connection to the telephone network.
