PCMFxUSB30 series

Common-mode EMI filter for differential channels with ESD protection

7.

Application information

The device is designed to provide high-level ESD protection and common-mode filtering

for differential high-speed data line pairs such as:

• USB 3.1

• HDMI 2.0

• Transition-Minimized Differential Signaling (TMDS)

• DisplayPort

• external Serial Advanced Technology Attachment (eSATA)

• Low Voltage Differential Signaling (LVDS)

When designing the PCB, give careful consideration to impedance matching and signal

coupling. Do not connect the protected signal lines to unlimited current sources like, for

example, a battery.

Since the SuperSpeed TX/RX lines are separated by GND or VBUS from the Hi-Speed

lines, PCMF1USB30 makes it easy to achieve same signal lengths, straight routing, and

optimal positioning for ESD protection directly at the connector.
