This is an LVCMOS-type signal with output high of 2.4V and output low of 0.4V.
If the Rx FOT does not see optical data on its PD (photo detector) for more than 5 us, the FOT is
switched into a sleep state where the main IC is switched off and the current consumption is
reduced to a maximum of 20uA. At this point there is no electrical output from the device. For a full
description of this function refer to the section Power Management Functions .
