1. HARDWARE
1.1
Introduction
The CDB5484U evaluation board provides a convenient means of evaluating the CS5484 energy measurement IC. The CDB5484U evaluation board operates from a single USB or 5V power supply. An optional 3.3V power supply input is available for powering the CS5484 directly. The evaluation board
interfaces the CS5484 to a PC via a USB cable. To accomplish this, the board comes equipped with a
C8051F342 microcontroller and a USB interface. Additionally, the CDB5484U GUI software provides
easy access to the internal registers of the CS5484. The software also provides a means to display the
on-chip ADC performance in the time domain or frequency domain.
1.2
Evaluation Board Overview
The board is partitioned into two main sections: analog and digital. The analog section consists of the
CS5484, passive anti-aliasing filters, and a high-voltage section with attenuation resistor networks. The
digital section consists of the C8051F342 microcontroller, LCD, test switches, reset circuitry, and USB interface. The board also has a user-friendly power supply connection. The assembly information and default configurations for jumpers are shown below.

Analog Section
The analog section of the CDB5484U is highly configurable. Onboard signal conditioning options for the
voltage and current channels enable most applications to interface directly to the sensors. The following
two sections define the voltage and current channel configurations.
1.3.1
Voltage Sensor Connection
There are three input signal options for the voltage channel inputs (VIN1±, VIN2±) which include an external low-voltage signal (via screw terminals or XLR connections), high-voltage line inputs, or GND.
Table 1 illustrates the options available.

The CDB5484U evaluation board provides screw-type terminals (J3 and J2) or XLR connectors (J30 and
J29) to connect low-voltage input signals to the voltage channels (see Figure 2). The screw terminals are
labeled as VIN1+ / VIN1- and VIN2+ / VIN2-. An R-C network at each channel input provides a simple
configurable anti-alias filter. By installing jumpers on J6 to position VIN1+, J11 to position VIN1-, J10 to
position VIN2+, and J9 to position VIN2-, the input voltage signal is supplied from the screw terminals or
XLR connections.

Digital Section
The digital section contains the microcontroller, USB interface, LCD, optical isolation, JTAG header, reset
circuitry, and external interface headers (J17 and J19). The microcontroller interfaces the UART or SPI of
the CS5484 with the USB connection to the PC, enabling the GUI software to access all of the CS5484
registers and functions.
1.4.1
Serial Port Selection
Communication to the CS5484 is provided through two serial port options: UART or SPI. It is necessary
to establish communication with the MCU before establishing a serial port communication protocol with
the CS5484 (see Figure 5).
Figure 5. MCU Connection Window
For UART communication, place the SSEL jumper to the UART position via J16, and select UART in the
serial port selection window. To enable SPI communications, place the SSEL jumper to the SPI position
via J16, and select SPI in the serial port selection window. Table 3 provides the serial communication options on the CDB5484U board.

CDB5484U
1.4.2
Interface to Microcontroller
Interface headers J17 and J19 are provided to allow the CDB5484U to be connected to an external energy
registration device or an external microcontroller. Interface header J17 provides direct access to the
CS5484 pins while interface header J19 provides an isolated connection. It is imperative to use the isolated connection (J19) when high-voltage signals are used. Failure to use isolation can result in damage
to components or electrical shock. Refer to “Digital Isolation” on page 10 for details on signal isolation.
Interface header J19 can be used to connect to the external microcontroller. To connect the CS5484 to
an external microcontroller, R34, R35, R36, R37, R38, R39, R40, R41, R42, and R43 must be removed
from the board.
1.4.3
Digital Isolation
Two types of isolation are provided, including a low-speed optical coupler for UART-only and high-speed
digital isolation for UART and SPI communication. Default jumper settings provide high-speed digital isolators. To enable high-speed digital isolators, place jumpers (J18 and J20) in the RX to DIGITAL position
and TX to DIGITAL position. To enable the high-speed digital isolators, it is also necessary to install jumper (J50) in the VDDA position. To enable low-speed optical UART communication, place jumpers (J18 and
J20) in the RX to OPTICAL position and TX to OPTICAL position.
The high-speed digital isolators operate from DC to 150Mbps. The low-speed optical couplers operate to
a maximum speed of about 4.8kHz. All the signals supplied to the isolators are available to the MCU except CPUCLK.
1.4.4
Additional Device Pin Access
The CS5484’s digital output pins (DO1, DO2, DO3, and DO4) are routed to LEDs, which provide a simple
visual check of the digital output. Jumpers J39, J40, J41, and J42 are equipped at the factory with jumpers
to enable the LEDs. The DO1 digital output pin is supplied to the digital isolation using jumper J49.
The MODE pin jumper (J15) should be installed in the VDDA to MODE position.
The CS5484 system clock can be connected to an onboard quartz crystal, or an external clock can be
supplied to the CS5484 XIN pin though jumper J48. To connect the onboard quartz crystal, install jumper
J43 in the XIN to CRYSTAL position. To connect XIN to an external clock, install jumper J43 in the XIN to
XIN_EXT position.

1.5
Power Supply Section
Table 4 illustrates the power supply connections on the evaluation board. The positive analog (VDDA) for
the CS5484 can be supplied using the +3.3V binding post (J36 and J37) or the onboard +3.3V regulator.
Jumper J38 allows the VDDA supply to be sourced from the +3.3V binding post (J37) or the regulated
+3.3V supply. The DC-DC converter (U8) powers the onboard +3.3V regulator. Jumper J26 allows the
+5V supply to be sourced from either the +5V EXT screw connector (J27) or the +5V USB supply. The
+5V supplies the power for the microcontroller (8051_REGIN) and the DC-DC converter (U8). Jumper J21
is used to measure the CS5484 analog supply current and must be installed.
When connecting the CDB5484U board to the AC line through non-isolated sensors, it is strongly recommended that the CS5484 GND reference is connected to the neutral, the non-isolated current sensor is
connected to the neutral, and the CS5484 is supplied by +3.3V isolated from AC line. The DC-DC converter (U8) provides 1kVDC isolation, while no isolation is provided for the 3.3V binding post connections.
If +3.3V is used from the binding post, then the external 3.3VDC power supply must be isolated from the
AC line. To prevent electric shock and damages, always use an isolated power source.

Typical Sensor Connections
The CDB5484U evaluation board provides connections directly to different types of sensors. Flexible onboard filter networks provide a convenient configuration for three common transducers: current shunt, current transformer (CT), or Rogowski coil.
1.6.1
Shunt Power Meter Example
An inexpensive current shunt configuration is easily achievable with the CDB5484U evaluation board.
Figure 6 depicts the voltage and current connections for a shunt sensor and its associated filter configurations.
It is strongly recommended that a low-side (neutral path) current shunt is used, especially in high-voltage
situations. Make sure that all signals are well connected before the power source is turned on. Extreme
care should be taken when connecting high-voltage signals to the CDB5484U evaluation board.

In this configuration it is unnecessary to use a burden resistor. A single anti-alias filter is all that is required
for the current channel. Below the filter corner frequency, the CS5484 inputs will see the same voltage
that is across the shunt. Therefore the shunt voltage should be kept below the maximum of 50mVp with
I-Channel PGA = 50x. A 10% margin is recommended for the shunt voltage (45mVp).

Current Transformer Power Meter Example
A slightly more expensive option is to use a current transformer (CT) to connect the AC current to the
CDB5484U evaluation board. Figure 7 depicts the voltage and current connections for a CT sensor and
its associated filter configurations.
NEVER “open circuit” a CT. Make sure that all signals are well connected before the power source is
turned on. Extreme care should be taken when connecting high-voltage signals to the CDB5484U evaluation board.
The burden resistor (R11/R22) is necessary in a CT application to convert the secondary current into voltage. Knowledge of the current transformers turns ratio (N) is key to determining the proper CS5484 input
voltage (Vburden) that the meter places on the system. The optimum secondary voltage (Vburden) at the
maximum current input should be 10% less than the maximum channel voltage of 250mVp with I-channel
PGA = 10x. The secondary voltage (Vburden) is determined by converting the primary current to the secondary current. Then the secondary current (Iburden) can be converted into a voltage by Ohm's Law.

sample rates. The frequency being used on the CS5484 should be entered in this box to provide accurate
frequency calculation in the FFT window. This will also help the software decide which functions the evaluation system can perform reliably.
2.5.1.5
Configuration Registers
In the Config0, Config1, and Config2 register boxes, the contents of the CS5484's configuration registers
can be modified by typing a hexadecimal value in the HEX field, or by changing any of the values below
the HEX field to the desired settings. Although the CDB5484U software allows the user to modify any of
the bits in the configuration registers, changing certain reserved bits, such as the NO_OSC bit of Config0,
may cause the software and board to behave erratically. This applies only to the CDB5484U evaluation
system, and not to the CS5484 chip itself.
2.5.1.6
Pulse Control Register
The Pulse Control Register section is used to make changes to, and display the contents of, the CS5484's
PulseCtrl register. The PulseCtrl register contains various bits used to select the input to each energy
pulse generation block within the CS5484. Refer to the CS5484 data sheet for descriptions of the bits.
The value of the PulseCtrl register is displayed in hexadecimal format. Most of the PulseCtrl register bits
are reserved or unused. Only the usable bits are displayed in the Setup Window.
2.5.1.7

The Epsilon section is used to display and adjust the Epsilon register (the ratio of the AC line frequency
to the output word rate). The Epsilon register can be updated either through entering the AC line frequency in the Line Freq field or by entering the direct register value in the HEX field.
2.5.1.12
ZXNUM
When Automatic Frequency Update is enabled, the ZXNUM section is used to adjust the number of zero
crossings used in the Epsilon calculation. The update rate of Epsilon is increased by reducing the zero
crossings. The register can be modified by typing the number of zero crossings.
2.5.1.13
Mask Register
The Mask Register box displays the value for the Mask register in hexadecimal and decodes them to indicate each bit's function. The Mask register can be modified by typing a value in the HEX field, or by
checking the appropriate boxes for the bits that are to be masked. The value present in the Mask register
may be changed by the GUI software during certain operations to provide correct functionality of the
CDB5484U board.
2.5.1.14
Temperature Registers
The Temperature Registers box is used to adjust the temperature offset register (TOFF) and temperature
gain register (TGAIN) to convert the temperature register (T) from the Celsius scale to the Fahrenheit scale,
or vice versa, and to improve temperature measurement accuracy. Refer to the CS5484 data sheet for
the details of the on-chip temperature sensor.
2.5.1.15
V/I Zero-crossing Level and No Load Threshold
The V/I Zero-crossing Level and No Load Threshold boxes display the values for these registers in hexadecimal and decimal. Each register can be modified by typing a value in the corresponding Decimal or
HEX field.
24
DS919DB5
CDB5484U
2.5.1.16
V1/V2 Sag, V1/ V2 Swell, and I1/I2 Overcurrent Registers
The registers for voltage sag, voltage swell, and overcurrent are displayed in the V1 Sag, V2 Sag, V1
Swell, V2 Swell, I1 Overcurrent, and I2 Overcurrent Register sections. These sections display the level
and duration values of the corresponding registers in both hexadecimal and decimal format. Each register
can be modified by typing a value in the corresponding decimal or HEX field. Refer to the CS5484 data
sheet for detailed descriptions of these registers.
2.5.1.17
Register Checksum, SerialCtrl Registers
The Register Checksum and SerialCtrl Register boxes provide control and status of critical serial port
communication parameters and the register checksum. The SerialCtrl Register section provides control
over RX pin, baud rate, and enabling checksum protection for serial communication. The Register Checksum section provides the calculated checksum of the critical registers inside the CS5484. The register
checksum updates automatically after single or continuous conversion has been performed. The RegChk
and SerialCtrl registers are displayed in hexadecimal form. Note that if the opto-couplers are selected as
the isolation (J18, J20), the maximum baud rate is 2400.
The baud rate field applies only to UART serial communication and can be changed by the pull-down field.
It is recommended to set the baud rate to the highest setting possible. The default setting of 600 baud will
cause some GUI functions to overflow the communication buffer and not function correctly.
2.6
Calibration Window
The Calibration Window is used to display and write to the CS5484 offset and gain calibration registers.
The user is also able to initiate the CS5484's calibration sequences that are used to set the calibration
values. AC offset, DC offset, and gain calibrations can be performed on the voltage channel, the current
channel, or both simultaneously. The user should refer to the CS5484 data sheet for more details on calibration (see Figure 20).
Figure 20. Calibration Window
DS919DB5
25
CDB5484U
The Refresh Screen button will update the contents of the screen by reading all the register values from
the part. It is recommended to click the Refresh Screen button when entering the Calibration Window, or
after modifying any registers to reflect the current status of the CS5484.
2.6.1
Save Cal and Load Cal Buttons
Clicking the Save Cal button will save the calibration widow's configuration to a .txt file. Clicking the Load
Cal button will recall a saved configuration and store values into the CS5484.
2.6.2
Offset/Gain Register
In the Offset and Gain Calibration boxes, the offset and gain registers for all channels are displayed in
hexadecimal and decimal formats. These registers can be modified directly by typing the desired value in
the display boxes. There are three types of offset registers: DC offset, AC offset, and power offset. The
AC offset registers only affect the RMS register values. The active and reactive power offset registers only
affect the active and reactive power register values, respectively. The DC, AC, and power offset registers
are two's complement numbers whose values range from -1 to +1. The gain register value ranges from 0
to 4.
2.6.3
Performing Calibrations
AC/DC offset and gain calibrations can be performed on both the voltage and current channels of the
CS5484. It is recommended to software-reset the CS5484 before running calibrations because the initial
values in the calibration registers will affect the results of the calibration. A software-reset will reset these
registers back to the default values of zero offset and unity gain. AC/DC offset calibration should be performed before gain calibration to ensure accurate results.
2.6.3.1
Offset Calibrations
1. Ground the channel(s) that need to be calibrated directly at the channel header(s), J6, J10, J11, and
J9 for the voltage channels and J7, J8, J13, and J14 for the current channels. The channel(s) could
also be grounded directly at the screw-type terminals.
2. Press the corresponding AC or DC offset calibrate button (Cal V, Cal I, or Calibrate All Channels) in
the corresponding Offset Calibration box(es).
3. The offset register value(s) will automatically update when the calibration is completed.
2.6.3.2
Gain Calibrations
1. Attach an AC or DC calibration signal to the screw-type terminals, and make sure the corresponding
channel headers (J6, J7, J8, J9, J10, J11, J13, and J14) are set to the desired input position.
2. Press the corresponding gain calibrate button (Cal V, Cal I, or Calibrate All Channels) in the corresponding Gain Calibration box(es).
3. The gain register value(s) will automatically update when the calibration is completed.
The Calibration window also contains the Active and Reactive Power Offset Register 1 and Register 2
display and adjustment. The user can read and write the values in the CS5484 active and reactive power
offset registers (P1OFF, P2OFF, Q1OFF, and Q2OFF).

2.7
Conversion Window
The Conversion Window allows the user to see the results of single and continuous conversions and the
CS5484 status, perform data averaging, and use the power-saving modes of the CS5484. The Conversion Window can be accessed from the System pull-down menu, Conversion menu item. The Conversion
Window provides the active, apparent, and reactive energy calculation register results for each channel.
In addition, the RMS, power factor, and peak signal amplitudes for each analog-to-digital converter channel, chip temperature (when temperature measurement function is enabled), AC line frequency (converted from the Epsilon register), and the values of each status register (Status0, 1, 2) are also displayed. The
Conversion Window also provides the total active, apparent, and reactive power register results.

Clicking this button will cause continuous conversions to be performed until the user clicks the Stop button. After each conversion is complete, the Result column will be updated with the values present in each
data register. The Mean and STD. DEV columns will be updated every N cycle, where N is the number in
the Samples to Average field. The user should stop continuous conversion before navigating away from
DS919DB5
27
CDB5484U
this window. The Continuous Conversion button should not be used with BAUD rates less than 1200Hz
in UART mode. Using lower BAUD rates (including the default 600 baud) will result in overflowing the
communication buffer and cause other window errors, communication failure, or both.
Data logging can be enabled using the DATALOG On/Off check box and Filename field.
2.7.3
Standby Mode Button
When this button is pressed, the CS5484 will enter a standby power-saving mode. To return to normal
mode, press the Power Up button. The user should power up the device before leaving this window.
2.7.4
Power Up Button
The Power Up button is used to send the wake-up command to the CS5484. The CS5484 will return to
normal operating mode.
2.7.5
Line Frequency Result
When the AFC bit in the Config2 register is set, the Epsilon register will be calculated automatically by the
CS5484, and the Line Frequency fields will be updated automatically in continuous conversion mode. If
the AFC bit in the Config2 register is not set and the line frequency is other than the default value (50Hz),
the line frequency must be set manually here to make Epsilon be the ratio of line frequency to the output
word rate (OWR). This ensures the accuracy of the quadrature power (Q1, Q2) and the reactive power
(Q1AVG and Q2AVG) calculations. Refer to the CS5484 data sheet for more details.

Analyzing Data
The evaluation software provides three types of analysis tests: Time Domain, Frequency Domain, and
Histogram. The time domain analysis processes acquired conversions to produce a plot of magnitude versus conversion sample number. The frequency domain analysis processes acquired conversions to produce a plot of magnitude versus frequency using the Fast-Fourier transform (results up to Fs/2 are
calculated and plotted). Also statistical noise calculations are calculated and displayed. The histogram
analysis processes acquired conversions to produce a histogram plot. Statistical noise calculations are
also calculated and displayed.

Histogram Information
The following is a description of the indicators associated with histogram analysis. Histograms can be plotted in the Data Collection window by setting the analysis type pull-down menu to Histogram. See
Figure 27. The histogram plot information includes:
• BIN: Displays the x-axis value of the cursor on the histogram.
• MAGNITUDE: Displays the y-axis value of the cursor on the histogram.
• MEAN: Indicates the mean of the data sample set. The mean is calculated using the following
formula:
n–1
i = 0 Xi
Mean = --------------------n
• STD_DEV: Indicates the standard deviation of the collected data set. The standard deviation is
calculated using the following formula:
n–1
STDDEV =
i = 0 Xi – Mean
2
-----------------------------------------------------n
• VARIANCE: Indicates the variance of the current data set. The variance is calculated using the
following formula:
n–1
i = 0 Xi – Mean
2
Variance = -----------------------------------------------------n
• MAXIMUM: Indicates the maximum value of the collected data set.
• MINIMUM: Indicates the minimum value of the collected data set.
