Stresses beyond those listed under âAbsolute Maximum Ratingsâ may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(AVCC = 5V, DVCC = DRVCC = 2.5V, GND = 0, INP and INN driven differentially with -2dBFS, CLKP and CLKN driven differentially
with a 2VP-P sinusoidal input signal, CL = 5pF at digital outputs, fCLK = 65MHz, TA = TMIN to TMAX, unless otherwise noted. Typical
values are at TA = +25°C, unless otherwise noted. â¥+25°C guaranteed by production test, <+25°C guaranteed by design and char-
acterization.)
