XE0046 Signal Descriptions
1
VCC
VCC provides the + 5 volt power source for the XE0046.
2
Vdd
Vdd provides the -5 volt power source to the XE0046
4, 8, 10, 16
Tip(n)
Tip provides the second connection to the telephone network (RJ11 Pin 3)
on each of the four internal DAAs. Tip has 1500 volts isolation from the rest
of the circuitry. This isolation must be preserved throughout the system.
6, 10, 14, 18
Ring(n)
Ring is one of two signals which form the telephone network connection
(RJ11 Pin 4) on each of the four internal DAAs. The XE1046 is not sensitive
to the polarity of the battery voltage on the telephone line. Ring has 1500
volts isolation from the rest of the circuitry which must be preserved
throughout the system.
20
GND
This signal is used as common reference for all of the control signals in the
XE0046. Signals on Tip and Ring are not referenced to ground.
21, 26, 31, 36
N/C
22, 27, 32, 37
/RI(n)
Ring Indicate, output, active low, TTL, RI provides a half-wave
representation of the Ring appearing on each telephone line.
23, 28, 33, 38
OH(n)
Hook-switch relay control an active high input. A high on OH closes the
internal relay within each DAA and connects the equipment to that telephone
line.
24, 29, 34, 39
RX(n)
RX is the analog output from each DAA. RX is referenced to ground. The
level of RX will be within 1 dB of the received signal on the telephone line.
25, 30, 35, 40
TX(n)
TX is the analog input to each DAA. The signal level at TX will be within 1
dB of the level of the transmitted signal on Tip and Ring. TX is referenced
to ground.
Pin
Name
Description
Note: The "n" designates the DAA with which the signal connects. Only power and ground signals are
common to all DAA's.
