Signal Buffers, Repeaters, Splitters FAQ

How does the PTN36241GHXZ handle power saving during USB 3.0 U2/U3 states?

The device detects link electrical conditions and dynamically activates or deactivates internal circuitry to enter power-saving states. In U2/U3 modes, it consumes approximately 1 mA, while the deep power-saving state reduces consumption to 2 µA when C1 and C2 pins are pulled LOW.

What is the function of the C1 and C2 control pins?

C1 and C2 are ternary input pins that control signal traces on their respective sides of the redriver. They allow users to select optimized settings for output swing, de-emphasis, and equalization gain based on whether the connected link requires optimization for short, medium, or long trace lengths.

Is the PTN36241GHXZ hot-plug capable?

Yes, the device is hot-plug capable and includes automatic receiver termination detection to manage connections dynamically without host software intervention.
