CYBL10562-56LQXI application field and working principle

CYBL10562-56LQXI RF Transceiver ICs is provided by Cypress Semiconductor Corporation. It is a single chip, low power, 2.4GHz IEEE 802.15.4 RF transceiver optimized for ZigBee and Thread applications. This article will discuss its application field and working principle.

Application Field

CYBL10562-56LQXI is suitable for low-cost, low-power wireless networks. As a radio single-chip solution, it integrates both the physical-layer (PHY) and MAC parts and supports 5MHz and 2.4GHz bands. The dedicated hardware accelerates fast, reliable data transfer, wich makes it ideal for various Internet of Things (IoT) protocols such as ZigBee, Thread, and 6LowPAN.

This chip not only supports several connectivity deployment models, including self-organizing mesh (SOM), star networks, and point-to-point, but also provides multiple security features and proprietary protocols, such as AES-128 quality of service, granting networks high performance and safety.

Working Principle

The basic block diagram of the CYBL10562-56LQXI chip is shown in the figure below. The chip can support all the functions needed to build a 2.4GHz IEEE 802.15.4 compliant radio system.

As for the working principle, the CYBL10562-56LQXI chip consists of both the radio part and the baseband processor. The Radio part is responsible for RF front-end components and the basic protocol processing while the Baseband processor consumes most of the system resources and supports the incoming/outgoing communication processing.

In the radio part, the Antenna Interface is used to connect one or two antennas to CYBL10562-56LQXI. The antennas can be either a chip antenna, an external antenna, or even a ceramic antenna. The RF Front-end subsystem is responsible for the transmission and reception of the radio waves. Additionally, it integrates LNA, preselector, LO buffer, T/R switch, and power amplifier (PA).

The Baseband Processor is the most important part of the radio system. It works as the controller of the radio part, and is used to support data process, including packet legacy and processing, data security, and network processing. It also includes a digital baseband processor, a MAC processor, a baseband RF-controller, an oscillator, and a voltage regulation module(VRM).

Conclusion

CYBL10562-56LQXI RF Transceiver ICs is an highly integrated single-chip radio solution ideal for low-power, low-cost wireless networks. Its main application fields are Internet of Things (IoT) protocols such as ZigBee, Thread, and 6LowPAN. It is a complete radio solution, with both Radio part and Baseband Processor, to support data process.
