in conjunction with semiconductor vendor recommendations, to allow
connections to various terminations (e.g. 75 or 120 Ω with the same
transformer). For example T1075NL 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. Similarly, 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 (5-8):(11-9) for Rx on the T1075NL.
ments specify minimum return loss levels. The transformers will
allow these limits to be complied within the situations where they
are applicable.

mit and receive transformers side by side, sufficient crosstalk attenu-
ation 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.
