Hello. I have a question.
What kind of method is there if I want to invert the input signal?
Also, if you want to connect logic before input, is there a suitable product for this device?

Hi,
What kind of method is there if I want to invert the input signal?
7.5.1.19 Inverting the Output Polarity -> Register 0x1f, bit 7
In some systems, the polarity of the data does not matter. In systems where it does matter, it is
sometimes necessary, for the purposes of trace routing, for example, to invert the normal
polarities of the data signals. The DS110DF111 can invert the polarity of the data signals by means of a register write. Writing a 1 to bit 7 of register 0x1f inverts the polarity of the output signal for the selected channel. This can provide additional flexibility in system design and board layout.
Also, if you want to connect logic before input, is there a suitable product for this device?
Thanks,

The customer wants to invert both the input and output of the signal polarity of this device.
Inversion of the output signal is possible with this device, but it seems impossible to invert the input signal.
Is there an inversion buffer that can match this device connected to INA_P, INA_N?
Or is there any other way?
Unfortunately there is no way to invert the input signal at the retimer level. Instead, the customer may invert the p and signals at the PCB routing level.
Thanks,
Rodrigo
