AD9852–SPECIFICATIONS

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.

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 V

DD 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.

Speciﬁcations subject to change without notice.

*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.
