Signal Buffers, Repeaters, Splitters FAQ

How does the PTN38007 handle power saving in USB3.2 modes?

The device detects LFPS/LBPM signaling to configure operation and dynamically activates or deactivates internal circuitry. It supports USB3.2 low power modes (U2/U3) with typical current consumption as low as 0.11 mA when one lane is enabled.

What is the maximum peaking gain supported by the PTN38007?

The PTN38007 supports a peaking gain of +20 dB at 10 GHz for Thunderbolt3/USB4 modes, +12.1 dB at 5 GHz for USB3.2 modes, and +20 dB at 10 GHz for DisplayPort modes.

Can the PTN38007 operate autonomously without host software intervention?

Yes, it performs autonomous orientation detection and adjusts equalization settings based on bus electrical conditions and snooped AUX/SB signals without requiring host processor intervention.
