Filter Addresses EMI on DisplayPort Interfaces
Featuring a wide-band thin-film common mode filter for EMI suppression on DisplayPort interfaces, The TCM1210U-500-2P from TDK, works as an EMI countermeasure on high-speed data transmission lines in notebook computers, audiovisual equipment and other electronic devices. With a measurement of 1.25 mm x 1.0 mm x 0.6 mm, this product is designed for suppressing noise on DisplayPort connections, a new standard for signal transmission between computers or audiovisual equipment and display monitors at speeds that exceed even 2.25 Gbit/s. A DisplayPort link uses up to four lines, each rated for 2.7 Gbit/s, resulting in a total transfer rate of 10.8 Gbit/s. Additionally, the filter has a cutoff frequency of 8.0 GHz, an impedance of 50 ohms (at 100 MHz), a rated current of 100 mA and rated voltage of 10 V.
