CM1693中文资料带 ESD 保护的 EMI 滤波器数据手册ONSEMI规格书

描述 Description

The CM1693 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six or eight filters (C-L-C) into a small-form factor, uDFN 0.40 mm pitch package. Each EMI filter channel is implemented as a 3-pole L-C filter, where the component values are 10pF-26nH-12pF. The CM1693's roll-off frequency at -6 dB attenuation is 300 MHz and can be used in applications where the data rates are as high as 140 Mbps. The CM1693 also provides greater than -30 dB attenuation over the 800 MHz to 6 GHz frequency range. The device includes ESD diodes on every pin that provide a very high level of protection for sensitive electronic components against possible electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±18kV, which is beyond the maximum requirement of the IEC61000-4-2 international standard.

特性 Features

• 700 MHz Attenuation, critical for LTE deployments
• SuppressedEMI assists in improving handset performance in Total Isotropic Sensitivity testing, a requirement to get agency and carrier approvals
• ±18kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)
• Protects against the most agressive ESD events

应用 Application

• Camera and display interfaces, keypad interfaces
• Emerging LTE and 4G protocols
• Cellular phones, notebook computers, netbook computers, portable navigation devices

简介

CM1693属于滤波器的EMI/RFI滤波器（LCRC网络）。由ONSEMI制造生产的CM1693EMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。
