PRELIMINARY TECHNICAL DATA
NOTES
1
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 affect device reliability.
2
Wake-Up Time refers to recovery from analog power down modes (see Power Down Modes of Operation). The longest time
required is for the Reference Clock Multiplier PLL to lock up (if it is being used). The Wake-Up Time assumes that there is no
capacitor on DAC_BP, and that the recommended PLL loop filter values are used.
3
SYSCLK refers to the actual clock frequency used on-chip by the AD9954. If the Reference Clock Multiplier is used to
multiply the external reference frequency, then the SYSCLK frequency is the external frequency multiplied by the Reference
Clock Multiplier multiplication factor. If the Reference Clock Multiplier is not used, then the SYSCLK frequency is the same as
the external REFCLK frequency.
EXPLANATION OF TEST LEVELS
I – 100% Production Tested.
II – 100% Production Tested at +25
°
C and sample tested at specified temperatures.
III – Sample Tested Only.
IV – Parameter is guaranteed by design and characterization testing.
V – Parameter is a typical value only.
VI – Devices are 100% production tested at +25°C and guaranteed by design and characterization testing for industrial
operating temperature range.

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 AD9953 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.
