PCMFxUSB3B/C series

Common-mode EMI filter for differential channels with integrated bidirectional ESD protection

9. Application information

The device is designed to provide high-level ESD protection for differential high-speed data line

pairs such as:

• USB 3.2

• HDMI 2.0

• Transition-Minimized Differential Signaling (TMDS)

• DisplayPort

• external Serial Advanced Technology Attachment (eSATA)

• Low Voltage Differential Signaling (LVDS)

When designing the Printed-Circuit Board (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.

connector evaluation dongle with PCMF1USB3B/C

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

PCMF1USB3B/C makes it easy to achieve same signal lengths, straight routing, and optimal

positioning for ESD protection directly at the connector.
