本次分享的是IC EMC EMI 测试项目的限值等级,整合了来自国外不同的规范的限值。一、TEM辐射发射测试(IEC 61967-2) 1、The requirement is class III (N, 12 dBµV) ¹; 2、 Limit line set for (G)TEM cell emission test method ²; 3、4 emissions levels are defined for the measurements, and consequent actions will be defined according the level measured ³; 二、1欧姆/150欧姆传导发射测试(IEC 61967-4) 1、CE 150Ohm global pins: 12-M¹ ; CE 150Ohm local pins: 10-K¹; (注意:这里没有对1Ohm法作要求哦!) 2、①conducted emission 150 Ω method limit line set for all IC function modules²; ②conducted emission 1 Ω method limit line set for all IC function modules²; 3、① 1 Ohm method limit³; ② 150 Ohm method limit³; 三、带状线辐射发射测试(IEC 61967-8) 1、 Limit: K (class III, 30 dBµV) ¹; Limit for 1161 MHz to 1289 MHz: 18 dBµV ¹; Limit for 1520 MHz to 1622 MHz: 18 dBµV ¹ ; (注意哦,这里对个别频率有要求了) This limit is calculated for IC Stripline with septum height of 6.7 mm¹ . 2、Limit line set for IC stripline emission test method²; 3、4 emissions levels are defined for the measurements³; 带状线辐射发射测试的限值在使用时一定要注意带状线小室所要求的高度是6.7mm。以上内容参考自: ¹:From 某车厂 EMC on IC-Level. ²:From Generic IC EMC Test Specification Version 2.1. 下载路径:Guideline Generic IC EMC Test Specification Version 2.1 (zvei.org) ³:From 某车厂 EMC Specification For ICs. |
