Signal Buffers, Repeaters, Splitters FAQ

How does the device handle inactive input signals?

When the input signal level falls below the active threshold (Vth-), the outputs are driven to the common mode voltage, effectively squelching the output.

What is the function of the EN# pin?

Setting EN# to 0 enables the channel for operation, while setting it to 1 places the device into a low-power standby mode.

Can the signal parameters be adjusted dynamically?

Yes, when I2C_EN is set to 1, equalization, output swing, and de-emphasis settings can be adjusted by programming the related registers via the I2C interface.
