AD9854–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 AD9854 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.

2The I and Q gain imbalance is digitally adjustable to less than 0.01 dB.

3Change in duty cycle from 1 MHz to 100 MHz with 1 V p-p sine wave input and 0.5 V threshold.

4Represents comparator’s inherent cycle-to-cycle jitter contribution. Input signal is a 1 V, 40 MHz square wave. Measurement device Wavecrest DTS – 2075.

5Comparator input originates from analog output section via external 7-pole elliptic LPF. Single-ended input, 0.5 V p-p. Comparator output terminated in 50

Ω.

6Simultaneous operation at the maximum ambient temperature of 85

°C and the maximum internal clock frequency of 200 MHz for the 80-lead LQFP, or 300 MHz

for the thermally-enhanced 80-lead LQFP may cause the maximum die junction temperature of 150

°C to be exceeded. Refer to the section titled Power Dissipation

and Thermal Considerations for derating and thermal management information.

7All functions engaged.

8All functions except inverse sinc engaged.

9All 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.
