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 log10 [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 (fS/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:

Signal to (Noise + Distortion) = (6.02N + 1.76) dB

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.

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.
