Signal Buffers, Repeaters, Splitters FAQ

How does the PI3EQX7841 handle low-level input signals?

The device includes input signal level detection and output squelch functions. If the input signal falls below the active threshold, the outputs are driven to the common mode voltage.

What is the power consumption profile of the PI3EQX7841?

The device is designed for low power operation with a typical consumption of approximately 330mW. It also features an auto slumber mode for adaptive power management and a standby mode for power-down states.

Can the equalization settings be adjusted dynamically?

Yes, when I2C control mode is enabled, equalization, output swing, and de-emphasis settings can be adjusted by programming the related registers via the fully programmable I2C interface.
