Signal Buffers, Repeaters, Splitters FAQ

How does the PI3EQX10964 handle configuration?

Configuration can be applied via pins, software through I2C, or loaded automatically via an external EEPROM upon power-up.

What is the maximum transmit de-emphasis capability?

The device offers programmable transmit de-emphasis up to 9 dB.

Can the receiver open a completely closed eye diagram?

Yes, the receiver is capable of opening an input eye that is completely closed due to inter-symbol interference introduced by the interconnect medium.
