R_ST establishes a threshold voltage at the ST_SET pin as shown in Figure 3-6. Internally, the input signal level is
monitored by the Level Detector which creates a DC voltage proportional to the input signal peak to peak value.
The voltage at ST_SET is internally compared to the signal level from the Level Detector. When the Level Detect
voltage is less than V_(STSET), LOS is asserted and will stay asserted until the input signal level increases by a
predefined amount of hysteresis. When the input level increases by more than this hysteresis above V_(STSET), LOS
15 ^{is deasserted. See the applications information section for the selection of RST.}
