PHY Chip (Physical Layer Chip) is the chip responsible for physical layer protocol processing in network communication, also known as baseband processing chip or RF chip. PHY chip realizes the functions of data reception, transmission, modulation and demodulation in network communication, converts digital signals into electromagnetic wave signals for transmission, and converts the received electromagnetic wave signals into digital signals for processing.
In network communication, PHY chips are usually integrated in communication devices, such as routers, switches, firewalls, etc., and can also be integrated in communication chips, such as Wi-Fi, Bluetooth, NFC, etc. The performance of PHY chip directly affects the speed and stability of network communication, so it is usually a crucial part of network communication.
Different network communication protocols and standards require different PHY chips to achieve, such as Ethernet PHY chip, wireless LAN PHY chip, fiber optic network PHY chip and so on. Therefore, the types of PHY chips are very rich, and choosing the right PHY chip according to different application scenarios and needs is a very important part of network communication.
PHY chip is the abbreviation of physical layer chip, also known as PHY device, mainly used in network communication, mainly responsible for demodulation and physical layer transmission related work. It is often a digital to analog converter or analog to digital converter, and amplifies and filters the electrical signal, controls the frequency transmission output power to implement complex channel encoding, decoding and other functions, and adjusts the end-to-end communication number of the digital host and the converter. It is used in local area networks, wide area networks, enterprise and links in solutions, such as PHY chips in communication standards such as Internet, WiFi, Bluetooth, etc.
The PHY chip is a physical layer switching chip, which is responsible for controlling the establishment and interruption of physical connections in the network. It uses Fiber, Ethernet and USB protocols to implement data transmission at the physical layer.

It can detect and adjust the transmission rate according to the type and strength of the signal to achieve low power consumption applications and high-speed data transmission; In addition, it can also control interfaces on different physical layers, such as optical fiber, Ethernet, USB, etc.
phy refers to the physical layer in osi.
phy chip is a device used to establish a path with the connected peer end before the communication two parties transmit signals. Such as the speed of the path.
