3 application typical application 1. et product - all coils have an et product of 10 v- sec minimum. 2. flammability - materials used in the products are recognized as ul94-vo approved. products meet the iec 695-2-2 requirements (needle flame test). 3. balance characteristics - the transformers meet the requirements for longitudinal balance of fcc part 68. 4. common mode rejection ratio - the cmrr for all transformers is better than 50db at 1mhz. a typical test circuit is shown below. 5. crosstalk attentuation - in the packages which contain transmit and receive transformers side by side, sufcient 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. 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. frequency 50-100 khz 10 khz-2mhz 2-3 mhz return loss transmit 9 db 15 db 11 db receive 12 db 18 db 14 b 7. surge voltage capability - all transformers and chokes meet surge voltage tests according to the most stringent regulatory documents, when used with the proper voltage and current suppression devices: metallic voltage: 800 v peak, 10/560 sec longitudinal voltage: 2,400 v peak, 10/700 sec 8. isolation voltage - 100% of transformers are tested during the specifed isolation voltage level. 9. general information - the transformers are specifcally designed for use 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 waveform, return loss, and balance. 10. common mode chokes - additional high-frequency 4-line common mode chokes may be used to provide an efective means of complying with national and international regulations on emi. the common mode chokes are designed to be used in conjunction with pulses t1/cept transformers as shown in the typical application below. crosstalk is typically -65 db or better. hp-8751a p1 p2 50:100 balun 100:50 balun xfmr 50:100 balun 100:50 balun xfmr hp-8751a p1 p2 100 100 t622.k (04/12) pulseelectronics.com t1/e1/cept/isdn-pri transformers quad port t1/e1 with 8 transformers, 1500 vrms
