Signal Buffers, Repeaters, Splitters FAQ

How does the device handle inactive channels?

When the corresponding channel's signal detector is idle for longer than 7.3ms, the device moves to Unplug Mode if no load is detected, or returns to Low Power (Slumber) Mode due to inactivity.

What is the function of the EN_x# pin?

Pulling EN_x# high places the device in a low-power standby mode. When EN_x# is low and the channel is operating, the input signal level determines whether the output is active.

Does the device support automatic receiver detection?

Yes, when the RXD-EN pin is pulled high, automatic receiver detection becomes active to manage connection states and power modes.
