The common mode chokes are designed to be used in conjunction with Pulse’s T1/CEPT transformers as shown in the typical application below. Crosstalk is typically -65 dB or better. 50:100 XFMR 100:50 BALUN BALUN Typical Application 5. Crosstalk Attentuation - In the packages which contain transmit and receive transformers side by side, sufficient crosstalk attentuation is achieved by the inherent characteristics of the toroid cores as well as by their proper positioning. The crosstalk attentuation is typically 65 dB or better. This result was established with the test circuit shown below. HP-8751A 50:100 BALUN P1P2 100 100 XFMR 100:50 BALUN 6. Return Loss - ITU-T G.703 and European national regulatory documents specify minimum return loss levels. The transformers will allow these limits to be complied with the situations where they are applicable.
