Hi,

What is the lockup time of the repeater after reset, i.e. how long does it take for TX to start transmitting?

Thanks,

Vladimir

Hi Vladimir,

There is no "reset" pin on the DS280BR820. It will begin transmitting the input signal as soon as the power reaches the recommended operating range.

Regards,

Lee

Thank you, Lee. Is there a diagram or datasheet on the timing between power level and the TX?

Hi Vladimir,

Sorry for the confusion. There is an additional "Power-on Reset" delay. The maximum delay is specified to be 60mS after the VDD reaches 2.375V.

Lee

Hi Lee,

Thanks for response. If the device has power on for long time, i.e. more than 60mS, what would be the delay from the moment there is signal on RX until it appears on TX?

Regards,

Vladimir.
