LMH1228: Output signal state after start / stop input signal

Hirokazu Takahashi

Part Number: LMH1228

Hello Support team,

In case of "ENABLE"=H (open), is the output signal state at "SDI_OUT" immediately stable after entering input signal to "IN0+/-"?

Is there any delay time for achieving the stable output?

In case of "ENABLE"=H (open), is the output signal state at "SDI_OUT" immediately go no signal condition after terminating input signal to "IN0+/-"?

Is there any delay time for going no signal condition?

Since the application will be monitor, we want to prevent to display unexpected image.

Best Regards,

Hirokazu Takahashi

    Greetings,

    Once ENABLE pin is asserted output signal becomes active. Please note ENABLE is true on high and there is internal pull up.

    To prevent unexpected image, we should disable ENABLE pin or pull ENABLE pin low. Then once the signal driving LMH1228 is stable, assert ENABLE pin(pull high).
