Tool/software:

What should be done with unused LVDS inputs on this part?

Section 9.2.3 describes an unused single ended LVPECL input, but there isn't any recommendation for an unused LVDS input pair.

    Hi Richard,

    Section 9.2.3 is showing an example of if you were send a single-ended LVPECL signal to the input of the device since this device supports LVPECL, CML, and LVDS signals as inputs. If you are not using one of the input channels on this device, you can tie the INx+ pin to Vcc and the INx- pin to GND to keep it in a known state (logic HIGH).

    Regards,

    Matt
