inductors and common mode chokes for use in adsl pots low pass filters performance description the series of coupled inductors shown on this data sheet are ideal for use in asymmetrical digital subscriber line (adsl) applications where a low pass filter is required to separate the voice frequencies from the data frequencies that are carried on an adsl line. in spite of their small footprint and low profile, these coupled inductors provide excellent electrical performance. they have stable inductance with varying dc current and temperature, high self-resonant frequency, low coupling capacitance, and excellent balance. the common mode chokes were developed to reduce common mode voltages in the low frequency range that is used for voice transmission. the chokes are also designed to accommodate dc currents up to 100 ma. application circuit the following schematic depicts a typical lc filter that incorporates the use of a common mode choke in addition to the lc network. as shown in the frequency response graph below, at low frequencies, the amplitude of the output signal is roughly equal to the amplitude of the input signal. at higher frequencies the amplitude of the output decreases. thus, the network passes low frequency voice signals with only a small degree of attenuation, while it suppresses high frequency signals and acts as a low pass filter. frequency response choke inductor inductor inductor capacitor capacitor capacitor input adsl & pots signals output pots signal only 100 hz 1 khz 10 khz 100 khz 10 db/ref 0 db -100 db 0 db www.pulseeng.com 4 b902.e (6/06) for more information: pulse worldwide headquarters 12220 world trade drive san diego, ca 92128 u.s.a. www.pulseeng.com tel: 858 674 8100 fax: 858 674 8262 pulse northern europe 3 huxley road surrey research park guildford, surrey gu2 5re united kingdom tel: 44 1483 401700 fax: 44 1483 401701 pulse southern europe zone industrielle f-39270 orgelet france tel: 33 3 84 35 04 04 fax: 33 3 84 25 46 41 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 road 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 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. pulse north china room 1503 xinyin building no. 888 yishan road shanghai 200233 china tel: 86 21 54643211/2 fax: 86 21 54643210
