4.0 System Level Description
4.1 System Overview
This section describes on how the chip being used to make up a complete system including the explanation on the 3rd party
components and how they work with the chip.
The PAH8011ET is based on CMOS optical technology that is designed to meet the requirements of heart rate monitor
accessories and wearables like smart watch or wrist band device. Figure 5 illustrates a system design for App Level diagram.
The processor is accessing PPG data from PAH8011ET chip, then pass it to App level. APP level applies PixArt provided
algorithm library to determine the heart rate data and waveform. Figure 6. illustrates a system design for Firmware Level
diagram. The processor will also access PPG data from PAH8011ET chip, then perform heart rate calculation with PixArt
algorithm library and send result to display or end device.
PAH8011ET can be configured to generate different frame rate settings.
