NOTES
1
Stresses above those listed under “Absolute Maximum Ratings” may cause perma-
nent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions extended periods may affect device reliability.
TERMINOLOGY
Sampling Rate
This is the rate at which the modulators on the receive channels
sample the analog input.
Output Rate
This is the rate at which data words are made available at the
RxDATA pin.
Integral Nonlinearity
This is the maximum deviation from a straight line passing through
the endpoints of the DAC or ADC transfer function.
Differential Nonlinearity
This is the difference between the measured and the ideal 1 LSB
change between any two adjacent codes in the DAC or ADC.
Dynamic Range
Dynamic Range is the ratio of the maximum rms input signal to the
rms noise of the converter, expressed logarithmically, in decibels
(dB = 20 log
10
[ratio]).
Signal to (Noise + Distortion) Ratio
This is the measured ratio of signal to (noise + distortion) at the
output of the receive channel. The signal is the rms amplitude of
the fundamental. Noise is the rms sum of all nonfundamental
signals up to half the sampling frequency (f
S
/2), excluding dc. The
ratio is dependent upon the number of quantization levels in the
digitization process; the more levels, the smaller the quantization
noise. The theoretical signal to (noise + distortion) ratio for a sine
wave is given by:

Settling Time
This is the digital filter settling time in the AD7013 receive section.
Bias Offset Error
This is the amount of offset in the receive channel ADC when the
differential inputs are tied together.
Receive Error Vector Magnitude
This is a measure of the rms signal error vector introduced by the
receive Root-Raised Cosine digital filter. This is measured by
applying an ideal transmit signal (i.e., an ideal
π
/4 DQPSK
modulator and an ideal transmit Root-Raised Cosine filter) to the
receive channel and measuring the resulting rms error vector.
Offset Vector Magnitude
This is a measure of the offset vector introduced by the AD7013 as
illustrated in the figure below. The offset vector is calculated so as to
minimize the rms error vector for each of the constellation points.

WARNING!
ESD SENSITIVE DEVICE
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
this device features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.
