DS90LV018A: common mode voltage range and common mode bias voltage

Part Number: DS90LV018A

Hi all

Would you mind if we ask DS90LV018A?

<Question1>
How much is the common mode voltage range?

<Question2>
Is there common mode bias voltage?

Kind regards,

Hirotaka Matsumoto

    Hi,

    The input common mode range extends from approximately 0V to 3V.  As the input common mode voltage approaches either of these endpoints, the differential amplitude must be reduced so voltages in excess of VCC and below GND are minimized.

    For LVDS devices the output is designed to produce a common mode voltage of approximately 1.2V.  This common mode voltage is used to set the common mode on LVDS inputs and gives them good noise immunity.

    Regards,
