... CDREF. AREF sets the DC operating point of the internal operational amplifiers and is the reference for the 1.235 comparator. If A5191HRT operates Semiconductor LM285A 1.235 V reference is recommended. The level at which CD (Carrier Detect) becomes active is determined by the DC voltage difference (CDREF - AREF). Selecting a voltage difference will set the carrier ...
