Murata Manufacturing Co., Ltd. (hereinafter ‘Murata’) has added a high cutoff frequency*1 product to its lineup of noise suppression components, the 0504-inch size (1.25 x1.0mm) chip common mode choke coils ‘‘DLM11C_HH2 Series’’ (hereinafter, ‘the product’), suitable for automotive high-speed differential interfaces such as LVDS*2, SerDes*3, USB, and HDMI. Murata has already started mass production of this product.
- *1High cutoff frequency: Reduces high-frequency noise.
- *2LVDS (Low Voltage Differential Signaling): An interface used for LCD panels.
- *3SerDes (Serializer/Deserializer): Circuits that convert between the serial and parallel signals in each direction.
In recent years, the automotive market has seen multiple USB ports installed in each vehicle seat as interfaces for connecting smartphones and PCs, and data transfer speeds have increased from conventional USB 2.0 to Gbps-class USB 3.2. For these differential interfaces, common mode noise suppression is essential, and small common mode choke coils that support high-speed signals are required. In response, Murata developed this product using proprietary lamination technology to reduce high-frequency noise above 7.5 GHz in a compact 0504-inch size.
