a pplication notes puls es interface modules provide the complete analog solution fo r 10base-t multiport applications in various packages. each module includes low pass filters, isolation transformers, and may contain common mode chokes. the 78z034cnl contains data and pre-equal- ization resistors on the transmit channel; and the receive channel is terminated with impedance matching resistors. electrical functions include: 1. impedance matching -t he low pass filters, in c onjunction with s elected resistor values, effectively m atc h the impedance characteristics of the ic to t hose of the t ransmission line. p recision wound i nductors help contro l passband impedances and lower return loss parameters. the proper cut-off frequency minimizes insertion loss and dela y distortion while maximizing attenuation in the stopband. 2. emi suppressio n -t he filter module is designed to contro l signal harmonics and jitter, reflections, crosstalk interferences, and common mode noise, which may contribute to radiated and conducted emissions. high impedance common mode chokes significantly minimize their effects. 3. equipment isolation - the t ransformer is d esigned to withstand 2000 vrms, ensuring protection from static charg e on the twisted pair line. each module is fully tested to ensure compliance with ieee 802.3 1993 standards. in some applications, such as multiport repeaters, many channels are in close p roximity. user compliance with fcc/cispr22 class b requirements can be achieved by applying rigorous design guidelines to suppress noise mechanisms. attention to high f requency signal paths, good pcb grounding techniques, and component placements are critical. a typical network interface card application is featured below. utp db-15 vc c aui xfmr aui port 10 base-t t ransceiver 1.2 k? 61.9 ? 422 ? 61.9 ? receiv e filter mdi port rj-45 txd+ cd xmt xmt xmt rcv rcv t ransmit filter 78z034cnl 422 ? td+ td- rd+ rd- xmt xmt xmt cd rcv rcv 49.9 ? 49.9 ? txp+ txd- txp- rxi+ rxi- vcc t ypical a pplication cir cuit 10b ase-t thr ough hole interf a ce modules for 802.3 10base-t lan applications note : modules are packaged in tubes. www.pulseeng.com 2 e104.f (8/10) for more information: pulse worldwide headquarters 12220 world trade dr. san diego, ca 92128 u.s.a. www.pulseeng.com tel: 858 674 8100 fax: 858 674 8262 pulse europe zeppelinstrasse 15 d-71083 herrenberg germany tel: 49 7032 7806 0 fax: 49 7032 7806 135 pulse china headquarters b402, shenzhen academy of aerospace technology bldg. 10th kejinan rd. high-tech zone nanshan district shenzen, pr china 518057 tel: 86 755 33966678 fax: 86 755 33966700 pulse north china room 2704/2705 super ocean finance ctr. 2067 yan an rd. west shanghai 200336 china tel: 86 21 62787060 fax: 86 2162786973 pulse south asia 135 joo seng rd. #03-02 pm industrial bldg. singapore 368363 tel: 65 6287 8998 fax: 65 6287 8998 pulse north asia 3f, no. 198 zhongyuan rd. zhongli city taoyuan county 320 taiwan r. o. c. tel: 886 3 4356768 fax: 886 3 4356823 (pulse) fax: 886 3 4356820 (fre) performance warranty of products offered on this data sheet is limited to the parameters specified. data is subject to change without notice. other brand and product names mentioned herein may be trademarks or registered trademarks of their respective owners. ? copyright, 2010. pulse engineering, inc. all rights reserved.
