Shenzhen Mingjiada Electronics Co., Ltd. supplies the KSZ9031RNXCA, a high-performance gigabit Ethernet physical layer transceiver (PHY) designed by Microchip Technology Inc., widely used in network communication equipment.
KSZ9031RNXCA Product Description:
The KSZ9031RNXCA is a fully integrated three-speed (10/100/1000 Mbps) Ethernet physical layer transceiver compliant with the IEEE 802.3 standard, suitable for data transmission over CAT-5 unshielded twisted pair (UTP) cables. The chip supports auto-negotiation functionality, enabling automatic adaptation to the optimal speed (10/100/1000 Mbps) and duplex mode (half-duplex/full-duplex).
KSZ9031RNXCA Product Features:
High Integration: The KSZ9031RNXCA integrates multiple functions, such as on-chip termination resistors and on-chip LDO controllers, requiring only one external FET to generate 1.2V for the core, simplifying circuit design and reducing system complexity and cost.
High Data Transfer Rate: The KSZ9031RNXCA supports three data transfer rates—10Base-T, 100Base-TX, and 1000Base-T—with a maximum speed of 1 Gbps, meeting high-speed data transfer requirements in various network environments and suitable for applications with high bandwidth demands.
Strong interface compatibility: The KSZ9031RNXCA features 3.3V RGMII/2.5V/1.8V voltage tolerance I/O, enabling compatibility with chips and devices of various voltage levels. This facilitates connection and integration with other hardware, enhancing system flexibility and scalability.
Strong auto-negotiation capability: The KSZ9031RNXCA features auto-negotiation functionality, automatically selecting the highest link uplink speed and duplex mode to ensure optimal transmission performance across different network environments and device connections, eliminating the need for manual configuration and reducing operational complexity and error rates.
Significant energy-saving effects: The KSZ9031RNXCA incorporates multiple energy-saving features, such as power-saving mode with energy detection, which reduces power consumption when the cable is not connected; support for Energy Efficient Ethernet (EEE), including Low Power Idle (LPI) mode, clock stop for 100Base-TX/1000Base-T, and reduced transmission amplitude for 10Base-Te options, effectively reducing energy consumption, improving the device's energy efficiency ratio, and lowering operational costs.
Rich diagnostic functions: The KSZ9031RNXCA features cable diagnostic functionality based on LinkMD TDR, enabling the identification of faulty copper cables and facilitating rapid identification and resolution of network connection issues, thereby improving the efficiency and reliability of network maintenance. It also supports diagnostic functions such as loopback mode, facilitating device testing and debugging.
High reliability: The KSZ9031RNXCA complies with ROHS3 standards, is lead-free, and is REACH-compliant, offering excellent environmental adaptability and safety. It can operate stably over a wide temperature range, with a maximum junction temperature of 125°C, a maximum operating temperature of 70°C, and a minimum operating temperature of 0°C, making it suitable for various industrial and commercial environments.
