QUICK START AND SETUP PROCEDURE
The recommended configuration for initial evaluation is shown
in Figure 2. The signal inputs can handle voltages from 0 V to
3.3 V. Power is supplied through the mini-B USB plug by
connecting it to any powered USB port.
4.
Synchronize the signal generator and the board by
connecting the reference clock output signal (available
through the P9 pins) to a trigger input on the generator.
The signal generation must be configured to start on this
trigger event (burst generation) or to lock to the reference
clock signal (RCK). The detailed configuration depends on
the specific source used.
Connect the signal generator to the IN+ terminal through
the P2 pins and enable the output.
To observe the demodulated signal, probe at P11 and P12.
P11 and P12 are arranged for differential scope probes, but
standard probes or clips work as well. Both the output
synchronization pulse (SYNCO) and RCK can be used to
trigger an oscilloscope.
Observe the filtered output by measuring the voltage
between P7 and P8 with a digital multimeter (DMM).
Set up the ADA2200-EVALZ by completing the following steps:

Power the board by plugging it into a PC or powered USB
hub. The green LED (DS1) turns on when power is
available.
Verify that the jumper configuration matches the settings
shown in Table 1. With this configuration, the IN+
terminal can be driven with a single-ended source.
Configure a signal generator to source a 6.25 kHz signal.
Offset the output voltage to make sure the signal remains
between 0 V and 3.3 V. An offset at midsupply (1.65 V)
allows maximum signal swing.
Note that many signal generators have a 50 Ω source
impedance and are configured for 50 Ω loads. Therefore,
the voltage swing doubles when the instrument is not
loaded with a 50 Ω impedance. This condition applies to
both the amplitude and offset setting. Verify the actual
signal output with a high input impedance scope before
connecting the signal generator to the ADA2200-EVALZ
board.

DETAILED BOARD DESCRIPTION
The ADA2200-EVALZ consists of the ADA2200 synchronous
demodulator, powered by the ADP151 3.3 V low dropout
(LDO) regulator. Power is applied through the mini-B USB jack
by connecting the supplied cable to a powered USB port, or by
using the +5V and GND test points adjacent to the USB port.
An on-board oscillator circuit uses a ceramic resonator (ECS,
Inc. ZTB400P [Y1]) to clock the ADA2200 at 400 kHz. This
oscillator circuit centers the band-pass filter at 1/64 of its clock
frequency, or 6.25 kHz. A different clock source and frequency
can be supplied through the CLKIN input, by placing the
jumper P13 between Position 1 and Position 2.
The input signal terminals are labeled IN+ and IN−. By default,
the ADA2200 is configured to be driven by a fully differential
source. The ADA2200 can be driven single-ended by applying
the signal between IN+ and ground, and connecting IN− to
VOCM through the P6 jumper (as shown in Table 1). Note that
the signal range for all the inputs and outputs is 0 V to 3.3 V;
exceeding this range on any input can damage the ADA2200.
There are two output signal terminals on the board. Probing
P11 or P12 with a scope displays the direct output signal from
the ADA2200. The P11 and P12 connectors are arranged to accept
a differential oscilloscope probe, but regular clips can also be
used. Connecting a voltmeter between P7 and P8 allows the
user to measure the dc signal after a 10 Hz, low-pass, RC filter.
The output terminals RCK and SYNCO can be used to
synchronize to the input and output signals, respectively. For
details on how to generate coherent signals or achieve
synchronization, refer to the Input Signal Synchronization
section and Output Signal Synchronization section. A summary
of the signals available on the board is shown on Table 2.
Note that the board includes pads for soldering side, launch,
SMA connectors (see Table 4 and the Johnson 142-0701-851
row). These connectors are commonly available for purchase
from electronic distributors.

SYNCHRONOUS DEMODULATION USING THE ADA2200
INPUT SIGNAL SYNCHRONIZATION
PROGRAMMING THE ADA2200
By default, ADA2200 filters and demodulates signals located
exactly at 1/64 of its clock frequency. For example, when using
the 400 kHz on-board oscillator, the demodulated signal
frequency must be 6.25 kHz. Because it is difficult to achieve
coherent, independently generated signals, the clock and the
signal source must be synchronized. This synchronization is
generally accomplished by deriving one signal from the other,
or by employing a phase-locked loop.
The ADA2200 has many programmable features, such as
multiple filter configurations, quadrature demodulation, and
adjustable clock ratios. These features can be programmed via
the serial port interface (SPI) or at power-up when booting
from an I2C EEPROM. For a complete list of features and the
internal register map, refer to the ADA2200 data sheet.
For this purpose, the reference clock signal (RCK) is derived
from the ADA2200 clock, and the default RCK frequency is
fCLK/64. Therefore, if the input signal is synchronized to RCK,
the band-pass filter is automatically centered on the input
signal, and the signal is properly demodulated. In addition,
this configuration allows the system to track any changes in
frequency, because everything is derived from a single master.
Because of these properties, it is possible to use RCK to drive a
signal excitation source, to trigger a pattern generation, or as
the frequency reference in a phase-locked loop generating the
input signal.
OUTPUT SIGNAL SYNCHRONIZATION
An output synchronization pulse is available on the SYNCO
connector. The ADA2200 generates this pulse every time the
output is updated and ready to be sampled. The frequency of
this pulse is 1/8 the clock frequency. By default, the pulse
polarity is positive, and it is generated 6.5 clock cycles after the
last output update.
When the ADA2200 is clocked by the on-board oscillator circuit,
the frequency of the SYNCO pulse is 50 kHz (20 µs period); the
pulse duration is one clock cycle or 2.5 µs (12.5% duty cycle);
and the pulse occurs 16.25 µs after the last output update. The
polarity and its occurrence relative to the output update event
are programmable features.
To program the ADA2200 via the SPI, use the ADA2200SDPEVALZ evaluation board.
SELECTING BETWEEN I AND Q DEMODULATION
COMPONENTS
By default, the ADA2200 performs synchronous demodulation
of the in-phase signal component (I). To demodulate the
quadrature component (Q), set the toggle switch to the
EEPROM_BOOT position and press the RESET button. The
EEPROM contains the same default configuration as the
ADA2200, but sets the quadrature demodulation bit.
The EEPROM must be configured to the factory contents.
Changing the EEPROM contents changes the behavior of the
device after switching the toggle switch.
DEFAULT FILTER CONFIGURATION
The ADA2200 internal filter is configured by default as a
second-order, band-pass filter, as shown in Figure 3.

The internal configuration memory is volatile, and the device
returns to its default value if it does not boot from the EEPROM.
Therefore, it is possible to toggle between the default and the
EEPROM configurations by selecting the appropriate position
of the toggle switch and by then pressing the RESET button.

On the ADA2200-EVALZ board, the SPI configuration option
is not directly available. The device can be reprogrammed
through the EEPROM option only. A valid configuration must
be loaded on the EEPROM, and the toggle switch must be on
the EEPROM_BOOT position at power up.
UG-702
ADA2200-EVALZ User Guide
The center frequency of the filter is located at 1/64 of the clock
frequency. As shown in Table 3, this is equivalent to 1/4 of the
Nyquist frequency of the output rate. With the on-board 400 kHz
oscillator, this center frequency is located at 6.25 kHz.
The ADA2200-EVALZ includes a 10 Hz low-pass filter, which
converts the demodulated signal to a dc voltage level. This
conversion makes it possible to use a simple voltmeter to
perform amplitude and phase measurements.
The filter transfer function scales with the input clock frequency.
Valid input clock frequencies range from 10 kHz to 1 MHz.
Sweeping the input clock frequency in this range sweeps the
filter center frequency from 156.25 Hz to 15.625 kHz. The filter
Q remains constant at 1.7 for any CLKIN frequency.
Amplitude Measurements
Connect Pin 1 and Pin 2 on P13 to use an external clock with
the device.
The relationship between the signal amplitude and the output
level depends on the relative phase between RCLK and the
signal. This relationship is analogous to measuring the
amplitude of a signal by looking at its crest (maximum
amplitude point) or zero crossing. When the signal amplitude
changes, the voltage at the crest sees the greatest change. In
contrast, the zero crossing remains at zero. Because these two
points are 90 degrees from each other, they are in quadrature.
Programming Different Filter Configurations
If the desired filter is different from the default definition, the
ADA2200 must boot from an EEPROM previously programmed
with valid contents for all the user registers. For additional details
on how to boot from EEPROM, refer to the Programming the
ADA2200 section.
For information on programming the EEPROM with a different
filter function, contact technical support.
SIGNAL MEASUREMENTS
The signal present at the output of the ADA2200 depends on
the amplitude and phase (relative to the reference clock) of the
signal applied at its inputs. When either the amplitude or phase
is known and constant, any output variations can be attributed
to the modulated parameter.
This dependence is shown in Figure 4. In any of these cases,
the ADA2200 is performing either amplitude or phase
demodulation.

If the relative phase of the signal makes the amplitude
measurement too small to measure, toggle the switch labeled
EEPROM_BOOT and press the RESET button. This action
allows the ADA2200 to boot with the EEPROM contents, which
are the same as the default configuration, except that the
ADA2200 demodulates the quadrature component instead.
Phase Measurements
If the amplitude of the signal present at the inputs of ADA2200
remains constant, the output varies as a function of the relative
phase between the signal and the reference clock (RCLK).
As long as the phase shifts are small, this relationship is
approximately linear; however, the gain (slope) of this
relationship depends on the relative phase shift between the
signal and RCLK. For example, if the phase shift occurs around
the crest of the signal, the change at the output is barely
noticeable. In addition, the user is not able to distinguish
between a positive and a negative shift. In contrast, the
maximum phase sensitivity is achieved when the phase shift
happens around the zero crossing. Because these two points are
90° from each other, they are in quadrature.
Δθ
ΔA1
If the phase of the signal present at the inputs of ADA2200
remains constant, the output behaves as a linear function of the
signal amplitude. In other words, if the amplitude of the signal
doubles, the output voltage also doubles.
Figure 4. Measurement Dependence on Phase and Amplitude Variations
If the relative phase of the signal makes the phase measurement
too small to measure, toggle the EEPROM_BOOT switch and
press the RESET button. This combination allows the ADA2200
to boot with the EEPROM contents, which are the same as the
default configuration, except that the ADA2200 demodulates
the quadrature component instead.

UG-702
Amplitude and Phase Measurements
When the amplitude and phase are unknown, it is necessary to
obtain two orthogonal components of the signal to determine
its amplitude, phase, or both. These two components are in
phase and in quadrature relative to each other; the popular
nomenclature used for these component is I and Q.
A signal with two known rectangular components can be
represented as a phase vector or phasor with an associated
amplitude and phase. This representation is show in Figure 5.
II
A = I 2 + Q2
θ = sin−1(Q/A)
Or, alternatively:
θ = cos−1(I/A)
The inverse sine or inverse cosine functions involving the I and Q
components linearize the relationship between the phase of the
signal and the measured angle. This calculation also makes it
possible to separate the effects of amplitude and phase variations.
I
A
Q
θ
Because the inverse sine and inverse cosine are only defined in
two quadrants, the sign of the I and Q components must be
taken into account to map the result to cover the entire 360°.
IV
12359-005
I
III
this switching is accomplished by toggling the EEPROM_BOOT
switch and pressing the RESET button. The dc voltage at the
output represents the I and Q components. Perform the
following calculations to find the amplitude and phase:
Figure 5. Signal Represented as Phasor
If the signal amplitude and phase are relatively constant for the
duration of the measurement, it is possible to switch the ADA2200
to return the I and Q components. On the ADA2200-EVALZ,
It is not recommended to use the inverse tangent function to
extract the phase information, because the function is not defined
at +90° and −90°. This function causes the phase measurement
to become very sensitive to measurement errors and noise.
