DESCRIPTION
The GS1T70-D540Fconverter has been designed
for the “U” interface of an ISDN-NTBA (Network
TerminationBasicAccess)systemwitheither4B3T
or 2B1Qstandard trasmission.
It meets the requirements of the following specifi-
cations:
EN 60950
CCITT I.430
CCITT G.960
CCITT G.961
ETS 300 002
ETS 300 012
ETS 300 047 (ISDN BASIC ACCESS, Safetyand
Protection)
Two isolated outputs, 5V/90mA and 40V/10.5mA
are supplied.Theconverteroffersshort-circuit pro-
tection (short-circuit on 40V output doesn’t affect
5V outputand the inputpower never exceedsthe
limit of thespecification), input eithervoltage polar-
ity,80%minimumefficiencyatmaximum load,input
and output filtering to meet very stringent noise
requirements.
The input and the output 2 (40V) stages are pro-
tected against differential overvoltage up to 1kV
(1.2/50
μ
s) and 250V (10/700
μ
s) respectively.
Whenthe inputvoltageis below 18V,the converter
offersaveryhighinputimpedanceandamaximum
quiescentcurrent of 10
μ
A.
These features allow the converter to operate di-
rectly connected to the telephone line without any
externalcomponents.
In addition, the wide operatinginput voltagerange
allows it to operate within the whole range of LT
(Line Termination) battery voltage and its relevant
lineresistance.
