ELECTRICAL CHARACTERISTICS The

denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. AVDD18, DVDD18 = 1.8V to 1.92V, AVDD33, DVDD33 = 3.135V to 3.465V,

SVDD = 1.71V to 3.465V, RFSADJ = 500, 12.5 load from IOUTP/N to GND including internal 50 termination, unless otherwise

specified.
