AFE5851: Input overload recovery time

Hi all,

When the Clamp is disable,
could you share the data of an input overload recovery time at  +12dB, +18dB and +24dB of overload?

Regards,
Toshi

    Toshi-san,

    I am assigning your post to the correct applications engineer. He should respond soon.

    Hi Amy-san,
    thanks for you support.

    I need to confirm the condition of an input overload recovery time.

    As my understanding, 
    The ADC full scale is 2Vpp, and 6dB input level is 4Vpp, isn't it?
    The analog supply voltage for ADC is 1.8V.
    It seems that an analog input  voltage of ADC is -0.3V to +2.1V as absolute maximum.
    And this is almost 4Vpp.
    So that, the test condition is less than 6dB input level.
    Is my understanding correct?

    If yes, I need to correct my question as below;

    When the Clamp is enable and an analog input level is 1Vpp,
    could you share the data of an overload recovery time at  +12dB, +18dB,  +24dB and  +32dB VGA gain? 
    This means as  VGA over load recovery time.

    I apologize to give you trouble.

    Best regards,
    Toshi
