The device supports all LOS functions for two receivers, and continually monitors for LOS of either channel. Four ADC channels monitor VCC, temperature, and two differential external monitor inputs that can be used to meet all monitoring requirements. Two digitalto-analog converter (DAC) outputs with temperatureindexed lookup tables (LUTs) are available for additional monitoring and control functionality.
