Are ADN4696E compatible with ADN4662?

Hello,

    are the ADN4696E/ADN4697E logic level compatibles with ADN4661/ADN4662?

Can I directly connect these 2 devices?

Thanks in advance

Maurizio.

  • Hello Maurizio,

    These devices are designed for different applications, the ADN4696E/ADN4697E are designed for multipoint LVDS communication (M-LVDS) and the ADN4661/ADN4662 for point-to-point LVDS.

     

    What application would you wish to connect these devices together in?

     

    The following assumptions can be made based on the datasheet specifications, though we have not tested connecting together these devices on a bus.

     

    The ADN4661 does not have a driver enable signal as this is not needed for a point-to-point link. ADN4696E/ADN4697E devices may receive the LVDS signals from the ADN4661 but the lower driver output levels of the ADN4661 would mean that the bus should not be too long or have too many receivers. Any ADN4696E/ADN4697E drivers on the bus would need to be disabled (DE low).

     

    The ADN4662 does not have a valid receiver output state for an idle bus (no active driver). However, if an ADN4696E/ADN4697E is used as an always enabled driver on the same bus, the ADN4662 may receive the LVDS signals.

     

    The digital logic levels on the ADN4661/ADN4662 and ADN4696E/ADN4697E are compatible.
