Signal Buffers, Repeaters, Splitters FAQ

How does the PI3EQX7502B handle low-power states?

The device enters a low-power standby mode when the enable pin is deactivated. It also features an automatic slumber mode that activates due to inactivity, returning to active operation upon signal detection.

What is the function of the RXD-EN pin?

When pulled high, the RXD-EN pin activates the automatic receiver detection function, which monitors signal presence and manages transitions between active and low-power modes.

Can the output emphasis be adjusted?

Yes, the device provides pin-configured output emphasis control, allowing users to adjust the signal characteristics to compensate for channel losses.
