Product Description
Microchip KSZ9031RNXIC Ethernet Transceiver is a high-performance, single-chip 10/100/1000 Mbps transceiver packed in a compact 48-pin QFN surface-mount package measuring 7 mm by 7 mm. It supports the RGMII interface with 3.3 V voltage tolerance and provides both full duplex and half duplex communication modes, making it versatile for various network designs.
This transceiver integrates on-chip termination resistors for all four differential pairs which reduces the complexity and cost of PCB design. An on-chip low-dropout (LDO) voltage regulator controller is included to generate a 1.2 V core supply from a single 3.3 V power input, requiring only one external MOSFET for core voltage provision.
Operating over industrial temperature ranges from -40°C to 85°C, this device includes an internal loopback mode for functional testing and diagnostics. It complies with the AEC-Q100 automotive standard, ensuring rugged reliability and suitability for automotive networking applications and harsh environments.
The KSZ9031RNXIC supports auto-negotiation functionality to select the highest available speed and duplex mode automatically (10/100/1000 Mbps). It also supports jumbo frames up to 16 KB and includes a 125 MHz reference clock output for timing synchronization.
This Ethernet transceiver is an excellent choice for industrial, automotive, and commercial use cases, including networking switches, routers, gateways, and embedded Ethernet applications that require robust and efficient data communication.
Supports 10BASE-T, 100BASE-TX, and 1000BASE-T standards. On-chip termination resistors for simplified PCB layout. Built-in LDO controller to power 1.2 V core from 3.3 V supply. Meets automotive AEC-Q100 qualification for reliability.
Wide operating temperature range from -40°C to +85°C. Internal loopback for diagnostics and testing. Compact 48-pin QFN surface-mount package, 7 mm x 7 mm footprint. RGMII interface compliant with version 2.0 timing. Jumbo frame support up to 16 KB for high throughput.
125 MHz reference clock output for synchronization. For more networking and semiconductor components, explore our Ethernet Transceiver category at EnvMart.
