TDK Launches Industry’s First Thin-Film Common Mode Filter for DisplayPort

July 15, 2008

Tokyo, July 15, 2008 – (JCN Newswire) – TDK Corporation announced today that it has developed a wide-band thin-film common mode filter for EMI suppression on DisplayPort* interfaces, an industry first.* The new product which carries the designation TCM1210U-500-2P will be available from this month.

The new filter measures 1.25 mm (L) x 1.0 mm (W) x 0.6 mm (T) in size and is designed specifically to suppress noise on DisplayPort connections, a new standard for signal transmission between computers or audiovisual equipment and display monitors at speeds that exceed even HDMI (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. The demand for EMI suppression components in this area is expected to grow significantly in the near future.

In order to create a product to meet this demand, TDK applied its industry-leading expertise in thin-film magnetic head technology (including original fine pattern conductor formation and film formation technologies). With a cutoff frequency of 8.0 GHz, the rating of the new filter is 2 GHz higher than that of the existing thin-film common mode filter for HDMI (TCM1210H-900-2P). As a result, the filter offers effective noise control without degrading the outstanding transmission characteristics of high-speed differential transmission line signals.

Main Applications-

EMI countermeasures on high-speed data transmission lines in notebook computers, audiovisual equipment, and other electronic devices.

Main Features-

1. Industry’s first common mode filter for DisplayPort interfaces

2. Cutoff frequency raised to 8 GHz to support high-speed data transmission

Main Characteristics-
