NOTES
1The reference clock inputs are configured to accept a 1 V p-p (minimum) dc offset sine wave centered at one-half the applied VDD or a 3 V TTL-level pulse input.
2Change in duty cycle from 1 MHz to 100 MHz with 1 V p-p sine wave input and 0.5 V threshold.
3Represents comparator’s inherent cycle-to-cycle jitter contribution. Input signal is a 1 V, 40 MHz square wave. Measurement device Wavecrest DTS – 2075.
4Comparator input originates from Analog Out section via external 7-pole elliptic LPF. Single-ended input, 0.5 V p-p. Comparator output terminated in 50 Ω.
5Important: In the 80-lead LQFP package simultaneous operation at the maximum ambient temperature of 85°C and at the maximum internal clock frequency at
200 MHz may cause the maximum die junction temperature of 150°C to be exceeded. Refer to the section of the data sheet entitled Power Dissipation section and
Thermal Considerations section for derating and thermal management information.
6All functions engaged.
7All functions except inverse sinc engaged.
8All functions except inverse sinc and digital multipliers engaged.

for industrial operating temperature range.
*Absolute maximum ratings are limiting values, to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure of
absolute maximum rating conditions for extended periods of time may affect device
reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9852 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
