芯凯电子扩充以太网供电系列产品——采用CMOS技术的两通道芯片KTA1550，四通道芯片KTA1552

时间： 2023-12-28 来源：KineticTechnologies（芯凯电子公众号）

技术问答

芯凯电子科技凭借其独有的专利技术——有源电磁干扰抑制和静电释放技术，为其以太网供电（PoE）系列产品再添新锐——两通道芯片 KTA1550，四通道芯片 KTA1552。

KTA1550，KTA1552芯片采用互补金属氧化物半导体（CMOS）技术，可用于抑制共模噪声和ESD保护，其结构和设计能在以太网产品中提供系统级的静电放电保护和电磁干扰抑制，以确保产品更好地满足电磁兼容性要求。

产品特点

KTA1550支持双绞线接口，16引脚TDFN封装，4mmx2.5mm的精巧尺寸有效节约空间，非常适用于10Base-T和100Base-TX应用（两个KTA1550适合1000Base-T应用）;

KTA1552支持四对双绞线接口，36引脚DFN封装，9mmx4mm的封装尺寸，适用于1000Base-T应用。

产品评价

“芯凯电子的专利有源扼流技术，为KTA1550和KTA1552系列产品带来卓越的共模降噪表现，同时并不会降低以太网性能。这一自适应持续抑制能补偿引起共模以太网噪声的变量，并可将系统中差模和共模的平衡改善多达10dB。”

芯凯电子科技副总裁David Nam“简而言之，从设计伊始，KTA1550、KTA1552就能满足系统设计师对电磁干扰发射和抗电磁干扰的要求，从而节省设计时间，并极大降低因设计修改而带来的成本。"

产品应用

芯凯电子科技电磁干扰抑制和静电放电产品系列的主要应用包括：

IP网络（VoIP）电话，网络摄像头，无线接入点（WAP），路由器和交换机机顶盒，网络打印机和网络家电，以及台式电脑和笔记本电脑等需要额外共模抑制以满足电磁兼容CLASS B或更高抗电磁干扰及静电放电要求的以太网系统。
