How to verify NFC antenna performance: Take PN7160 as an example

In card reader mode, we can verify through the NCI command defined in PN7160. We can perform verification control through PN7160's own commands.

What is symmetrical tuning and asymmetrical tuning

In standard antenna designs, we use cutoff frequencies up to 22 MHz to provide correct detuning and loading behavior of the antenna. This high cutoff frequency helps meet the minimum and maximum field strength limitations of common antennas without the need for dynamic power control (DPC)

Semtech PerSe (Person Sensing) Error Detection and Configuration

In SAR applications, Semtech SX9331 CAP sensor can detect whether a human body is approaching. When a human body is approaching or moving away, SX9331 sends an interrupt notification to the Host or DSP, and the Host or DSP decides whether to reduce the RF power to ensure that the human body receives The electromagnetic radiation received will not exceed the standard to ensure compliance with SAR regulations.

Type-c Thunderbolt introduction

Thunderbolt utilizes the USB Type-C connector as a physical interface, but provides more advantages in performance and functions.

It provides accurate acceleration measurements and is widely used in various applications that require acceleration detection, such as consumer electronics, industrial equipment, motion tracking, automotive electronics, etc.

Why PCB controls 50 ohm impedance

single-ended network in the design is generally controlled by 50 ohms, so many people will ask, why is it required to be controlled by 50 ohms instead of 25 ohms or 80 ohms? First of all, 50 ohms is selected by default, and everyone in the industry accepts this value. Generally speaking, it must be a standard set by a recognized organization, and everyone designs according to the standard.

Using the reference clock to realize serial communication data recovery of Cyclone10LP devices

In the non-source synchronous low-speed serial data communication scenario, the clock frequency of the communication counterpart may be biased, which may cause the data receiving end to be unable to accurately sample. In this case, the SOFT-CDR and DPA functions in the high-speed transceiver or LVDS serdes of high-end Altera devices can effectively solve this problem.
