transformers (-40°C to +85°C operating temperature range), OCL (Open Circuit
Inductance for the primary winding) is specified at both -40°C and +25°C.
At -40°C, OCL is 600 µH minimum for all low temperature models with the
exception of PE-68827NL which is 800 µH minimum and PE-65836NL which is
300 µH minimum. All other parameters are specified at +25°C only. Standard
temperature range is 0°C to +70°C.

receive transformers side by side, sufficient crosstalk attenuation is achieved
by the inherent characteristics of the toroid cores as well as by their proper
positioning. The crosstalk attenuation is typically 50 dB or better from 100 kHz
to 10 MHz. This result was established with the test circuit shown below.

in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary rate (PRI) interface
applications. They are matched to the majority of the line interface transceiver
ICs currently available. Use of the proper transformer allows the interface
circuit to comply with ITU-T G.703 and other standards regarding pulse wave-
form, return loss, and balance.
chokes shown in this data sheet provide an effective means of compliance
with national and international regulations on EMI. They are designed to be
used in conjunction with Pulse’s T1/CEPT transformers as shown in the typical
application below. Crosstalk is typically -70 dB at 1 MHz and -55 dB at 10 MHz.

conjunction with semiconductor vendor recommendations,
to allow connections to various terminations (e.g. 75 Ω or
120 Ω with the same transformer). For example T1075NL
can be used with the Siemens PEB 2235 to achieve
connection to the 75 Ω or 120 Ω cable. For 75 Ω termination,
the PEB 2235 requires the following turns ratio: 1:1.57 (TX)
and 1:1.26 (RX) which can be achieved using pins (1-2):(15-
16) for TX and (10-11):(5-8) for RX. For 120 Ω, the following
turns ratio are required: 1:2 (TX) and 1:1 (RX), which are pins
(1-2):(16-14) for TX and (9-11):(5-8) for RX on the T1075NL.
