t1/e1/cept/isdn-pri interface modules dual surface mount transformer modules, 1500vrms, extended temperature range 1. extended temperature range models ? for extended temperature range transformers (-40c to +85c operating temperature range), ocl (open circuit inductance) is specified at both -40c and +25c. at -40c, ocl is 600 h minimum. all other parameters are specified at +25c only. standard temperature range is 0c to +70c. 2. turns ratio is specified primary: secondary (ct = center tap). 3. standard packaging for the surface mount package is anti-static tubes. optional tape & reel packaging can be ordered by adding a ? t ? suffix to the part number, (i.e. t1220 t ). 1. et product ? all coils have an et product of 10v-sec minimum. 2. flammability ? materials used in the products are recognized as ul94-vo approved. products meet the require- ments of iec 695-2-2 (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 attenuation ? in the packages which contain transmit and receive transformers side by side, sufficient crosstalk attenuation is achieved by the inherent characteris- tics of the toroid cores as well as by their proper positioning. the crosstalk attenuation is typically 65db 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 within the situations where they are applicable. frequency 50-100khz 100khz-2mhz 2-3mhz return loss xmit 9 db 15db 11db rcv 12db 18db 14db 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: 800v peak, 10/560sec longitudinal voltage: 2,400v peak, 10/700sec 8. isolation voltage ? 100% of transformers are tested during production to the specified isolation voltage level. 9. general information ? the transformers are specifically designed for use in 1.544mbps (t1), 2.048mbps (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. transformer selection guide ? please contact pulse application engineering or see our website for the latest pulse transformer selection guide. notes from tables application notes 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 south asia 150 kampong ampat #07-01/02 ka centre singapore 368324 tel: 65 6287 8998 fax: 65 6280 0080 pulse north asia no. 26 kao ching rd. yang mei chen taoyuan hsien taiwan, r. o. c. tel: 886 3 4641811 fax: 886 3 4641911 pulse china headquarters no. 1 industrial district changan, dongguan china tel: 86 769 85538070 fax: 86 769 85538870 pulse north china room 1503 xinyin building no. 888 yishan rd. shanghai 200233 china tel: 86 21 54643211/2 fax: 86 21 54643210 pulse europe einsteinstrasse 1 d-71083 herrenberg germany tel: 49 7032 7806 116 fax: 49 7032 7806 135 www.pulseeng.com t660.b (6/06) performance warranty of products offered on this data sheet is limited to the parameters specified. data is subject to change w ithout notice. other brand and product names mentioned herein may be trademarks or registered trademarks of their respective owners. ? copyright, 2006. pulse engineering, inc. all rights reserved.
