Using a Pre-Calibrated Temperature Sensor in PHY1070-Family SFP

Abstract: For temperature digital-diagnostic monitoring (DDM) calibration, standard Phyworks PHY1070/PH1071/PHY1075/PHY1076 SFP reference designs require that ADC samples be taken over multiple temperature points. However, one SFP module design for the Phyworks optical transceivers does not need multitemperature calibration. The solution also does not require direct probing of the module.
