Overview
2.1
Introduction
NOTE: From this point on, unless otherwise noted, AFE44x0 refers to AFE4400- and AFE4490based demonstration kits.
The EVM is intended for evaluating AFE4400 and AFE4490 devices. The family of devices consist of a
low-noise receive channel, the LED transmit section, and diagnostics for sensor and LED fault detection.
The AFE44x0 has a highly configurable timing controller, enabling complete control of the device’s timing
characteristics. The device also has an integrated oscillator working off from two clock sources: either an
external crystal or the clock from an external host processor to ease clocking requirements and provide a
low-jitter clock to the AFE44x0. The device communicates to the external host processor using the serial
peripheral interface (SPI). The purpose of the EVM is to expedite evaluation and system development
activities related to AFE44x0 devices. The AFE4490SPO2EVM demonstration kit is shown in Figure 1.
Figure 1. AFE4490SPO2EVM Demonstration Kit
The board can be assembled with either of these devices. Check the TI website for the
AFE4400SPO2EVM and AFE4490SPO2EVM demonstration kits. The MSP430 firmware and PC
application are designed to automatically detect and configure to the installed part.
Throughout the document, the term demonstration kit is synonymous with AFE44x0SPO2EVM.

Installing the USB Drivers
The communication interface between the AFE44x0SPO2EVM board and PC is through the USB, using
the CDC profile. A one-time installation of the USB driver is required for the communication between the
AFE44x0SPO2EVM and PC application.
NOTE: For Windows 8, signed driver enforcement may have to be disabled. Section 3.3.1 explains
how to do this.
Following these steps ensures proper installation of the USB drivers:
1. Plugin the USB-to-mini USB cable to J4 of AFE44x0SPO2EVM and the other end to the USB port on
the PC.
2. Win XP OS starts up the New Hardware Wizard to enable the user to install the USB driver for the new
hardware. The Windows 7 or Windows 8 OS attempts to find the driver for the new hardware found
automatically and if the driver is not found, there is no pop-up message to indicate that the driver
installation failed. In the Windows 7 or Windows 8 OS, click on Device Manager, right click on
MSP430-USB example under Other devices and click on Update Driver Software as shown in
Figure 8. This step is not required for the Windows XP OS.

in the Test Results section, which is a pop-up window that opens when the Scope Analysis button is
clicked. The Scope Analysis: Test Results section pop-up window is shown in Figure 32.
By selecting the FFT plot, the data are displayed in the frequency domain by performing an FFT on the
channel selected. Details of the FFT (including SNR, THD, and so on) are shown in the Test Results
section located in the left side of the GUI.
Selecting the Histogram plot displays the data in a histogram format for the channel selected. The data
are arranged in the total number of histogram bins set within the tab following acquisition. The histogram
analysis (shown in the Test Results section of the GUI) is used to view the mean voltage, root mean
square (RMS) voltage, and peak-to-peak voltage.
Four plot modes can be selected: Single Plot mode, Double Plot mode, Three Plot mode and Four Plot
mode. In Single Plot mode, only one plot (Time, FFT, or Histogram) can be viewed and analyzed for post
processing. In Double Plot mode, any two plots (Time, FFT or Histogram) can be viewed and analyzed. In
Three Plot mode, any three plots and in Four Plot mode, any four plots (Time, FFT or Histogram) can be
viewed and analyzed.
The following algorithms have been used to find the # of samples for FFT calculation:
(a) # of samples for FFT calc. which is power of 2 ≤ min ( (Data rate (sps) × N where N is the value in the
"Show data for the last N secs" column) , No. of samples )
(b) If ( (# of samples for FFT calc. == No. of samples) && (Filter Type == “None”) ) then # of samples for
FFT calc. = No. of samples
(c) If ( (# of samples for FFT calc. == No. of samples) && (Filter Type == “Notch”) ) then # of samples for
FFT calc. = No. of samples / 2. This is to allow for filter settling.
(d) If ( # of samples for FFT calc. < 32 samples ) then an error msg “Insufficient # of samples for FFT
calculation” will be displayed.
Examples:
1. No. of samples = 8192
Data rate (sps) = 500
Show data for the last 5 secs
Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 × 5) , 8192 )
2. No. of samples = 8192
Data rate (sps) = 500
Show data for the last 8 secs
Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 x 8) , 8192 )
3. No. of samples = 8192
Data rate (sps) = 500
Show data for the last 20 secs
# of samples for FFT which is power of 2 = 8192 ≤ min ( (500 x 20) , 8192 )
Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = None) then # of
samples for FFT which is power of 2 = 8192
Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = Notch) then # of
samples for FFT which is power of 2 = 8192 / 2

Power Supply
AFE4490 can operate from 2.0- to 3.6-V Rx analog supply (RX_ANA_SUP), 2.0- to 3.6-V Rx digital supply
(RX_DIG_SUP), 3.0- to 5.25-V Tx Control supply (TX_CTRL_SUP) and LED driver supply
(LED_DRV_SUP).
AFE4400 can operate from 2.0- to 3.6-V Rx analog supply (RX_ANA_SUP), 2.0- to 3.6-V Rx digital supply
(RX_DIG_SUP), 3.0- to 3.6-V Tx Control supply (TX_CTRL_SUP) and LED driver supply
(LED_DRV_SUP).
The power for the board is derived from the USB input (J4) through a forward-biased diode (D5) to avoid
reverse current flow. The USB data bus is ESD protected using TI’s ESD protection diode array
TPD4E004DRYR (U7). The USB VBUS is fed to the integrated Li-ion linear charger and system powerpath management module, BQ24032ARHLR (U12), which generates greater than 4.2-V output
(VCC_BAT). This output is fed to TI’s low-input boost converter with integrated power diode and
input/output isolation, TPS61093 (U9), for generating a boosted voltage of 8.97 V. This output is fed to
low-noise voltage regulator LP3878-ADJ (U8) for generating 5 V for the LED_DRV_SUP and
TX_CTRL_SUP for AFE4490 EVM and for generating 3.3 V for the LED_DRV_SUP and TX_CTRL_SUP
for AFE4400 EVM. The boost converter output is also fed to the ultralow-noise linear voltage regulator
TPS7A4901DGN (U13) for generating 3 V for the RX_ANA_SUP and RX_DIG_SUP. The boost converter
output is also fed to the ultralow-noise linear voltage regulator TPS7A4901DGN (U14) for generating 3 V
for MSP_DVCC and MSP_AVCC.
The inductors L2, L2, L4, and L5 are used to minimize the power supply noise induced by the power
supply regulators.
Test point and series jumper resistors are provided to make sure the power supplies to the board are
correct. The corresponding voltages on AFE4490SPO2EVM are given in Table 2. The corresponding
voltages on AFE4400SPO2EVM are shown in Table 3.

10.4 Using an External ADC (Bypass ADC Mode) (Available Only for AFE4490 Device)
AFE4490 has a mode where the front-end analog output voltage becomes available on two pins
(RX_OUTP, RX_OUTN), around a common-mode voltage of about 0.9 V. In this mode, the internal ADC
of AFE4490 is disabled, one of the internal ADC_RESET clocks is brought out on the PD_ALM pin
(PD_ALM is monitored at series jumper resistor R37). This signal is used to convert each of the four
phases (with every pulse repetition period). Additionally the ADC_RDY signal (ADC_RDY is monitored at
series jumper resistor R26) is used to synchronize the external ADC with the AFE.
10.5 Diagnostics
The device includes diagnostics to detect open or short conditions of the LED and photo-sensor, LED
current profile feedback, and cable on or off detection. The EVM supports the diagnostic feature of the
device.
The diagnostic feature is enabled from the Global Settings under the Device Configuration tab. Clicking
the Diagnostic Enable button enables the diagnostic function and once the diagnostic function is
completed, the status of the fault flags are updated on the Global Settings tab. Figure 48 shows the
diagnostic mode fault flags when no finger pulse oximeter sensor was connected to the EVM.

Framework 3.5 installation to fail. Install the .NET Framework 3.5 before installing any Windows
language packs. (Source: http://msdn.microsoft.com/library/hh506443(v=VS.110).aspx)
There are two methods to resolve this.
10.8.1
Method 1 (Enabling the .NET Framework 3.5 in Control Panel)
In Control Panel, choose Programs and Features, choose Turn Windows features on or off, and then
select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box. This option requires an Internet
connection. The user does not need to select the child items.

Method 2 (Enabling .NET Framework 3.5 on Windows 8 in Offline Mode)
This is basically using Windows 8 CD to enable/install .NET FRAMEWORK 3.5 in the PC. This method
does not require an internet connection.
Step 1: Insert Windows 8 DVD or mount ISO image. The source of this feature can be found in folder
E:\sources\sxs. (In this case E: is the user’s drive letter on which the user has loaded Windows 8 Media.)

10.9 COM Port
It has been observed that on certain machines, the GUI will not work for lower COM ports. When the GUI
and the USB drivers are installed correctly and the Device Manager shows the AFE44x0SPO2EVM
recognized as a virtual COM port, but the GUI cannot establish communication to the AFE44x0SPO2EVM
and shows the Device Communication Error, change the COM port to a higher number (greater than 25).

documentation (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance with the terms and conditions set forth herein.
Acceptance of the EVM is expressly subject to the following terms and conditions.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms and conditions that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.

Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms and conditions do not apply to Software. The warranty, if any, for Software is covered in the applicable Software
License Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for any defects that are caused by neglect, misuse or mistreatment
by an entity other than TI, including improper installation or testing, or for any EVMs that have been altered or modified in any
way by an entity other than TI. Moreover, TI shall not be liable for any defects that result from User's design, specifications or
instructions for such EVMs. Testing and other quality control techniques are used to the extent TI deems necessary or as
mandated by government requirements. TI does not test all parameters of each EVM.
2.3 If any EVM fails to conform to the warranty set forth above, TI's sole liability shall be at its option to repair or replace such EVM,
or credit User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the
warranty period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to
repair or replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall
be warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
