S not connected
I input for setting threshold level of LOS detector; threshold level is set by
connecting external resistors between pins VCCA and Vref; when forced to
GNDA or not connected, the LOS detector is switched off
I not connected
− not connected
I input for setting AC level of the output circuit; output signal level is set by
connecting external resistors between pins VCCA and Vref; when forced to
VCCA or not connected, pins OUT and OUTQ will be switched off
I not connected
O reference voltage for programming output level circuit and LOS threshold;
typical value is VCC − 1.6 V; no external capacitor allowed
− not connected
I for test purposes only; to be left open-circuit in the application
