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-68827 which is 800 µH minimum and PE-65836 which is
300 µH minimum. All other parameters are specified at +25°C only. Standard

in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary rate (PRI) inter-
face 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 waveform, 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 appli-
cation below. Crosstalk is typically -70 dB at 1 MHz and -55 dB at 10 MHz.

to allow connections to various terminations (e.g. 75 or 120
Ω with the same transformer). For example T1075 can be
used with the Siemens PEB 2235 to achieve connection to
the 75 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 T1075.
