Part Number: AFE4403 we collect the SpO2 data from SPI bus from FPGA, such as
red_led
infrared_led
red_ambient
infrared_ambient
red_diff
infrared_diff
i would like to lean how to correlate these parameters to the datasheet from AFE4403…

Part Number: AFE4403 i am seeking recommendation in setting up a test condition with prosim 8 to evaluate the reliability performance difference on Integrated Analog Front-End for Heart Rate Monitors and Low-Cost Pulse Oximeters (AFE4403)
Thanks for the help.
After 5 exceptions by the PCB manufacturer, i was able to provide them a Gerber that they were able to fabricate.
here is the result.
I did it in only 2 layers.
and the end result
Hi,
For Question#2 "my " TX_CTRL_SUP = LED_DRV_SUP = 4.9V". I am powering the EVM using USB port (J4) from the PC. Is this fine?"
" TX_CTRL_SUP = LED_DRV_SUP = 4.9V" are within the datasheet spec range.
"powering the EVM using…
Part Number: AFE4403 I have a question about AFE4403. Depending on the circuit configuration and software SPO2 (Blood Oxygen Saturation) and HRM (Heart Rate per Minute) Can you measure at the same time?
If possible, where in the datasheet the circuit configuration…
Hello Matthew,
It's been two weeks since a response, I'll be closing out this post since I assume the problem has been solved.
Feel free to reply to open this thread, or make a new one for continued support.

Hi,
Is it possible to get PPG and Heart rate samples at the same time?
I am using AFE4403EVM here and I am able to access sensor data in GUI, Using SFH7050, there is constant RED light ON.
Do I need to enable GREEN light for HR…
