Signal Buffers, Repeaters, Splitters FAQ

How does the device handle inactive signals?

When the input signal level falls below the active threshold (Vth-), the outputs are driven to the common mode voltage. Additionally, if the signal detector is idle for longer than 7.3ms, the channel may move to Unplug Mode or return to Low Power Mode.

What is the power consumption profile?

The device consumes approximately 330mW during normal operation. It includes an auto slumber mode for adaptive power management and a standby mode that acts as a power-down state when enabled.

Can the equalization settings be adjusted?

Yes, the PI3EQX7502M provides programmable equalization and pin-configured output emphasis control to optimize performance over different physical mediums.
