Microchip KSZ9896 6-Port Gigabit Ethernet Switch Chip Product Introduction | Mingjiada Electronics: Genuine Products in Stock
Product Overview
The Microchip KSZ9896CTXI is a highly integrated, Layer 2 managed six-port Gigabit Ethernet switch chip from Microchip Technology’s KSZ9896 series. This device integrates five 10BASE-Te/100BASE-TX/1000BASE-T physical layer (PHY) transceivers and associated MAC units. It also features a configurable GMII/RGMII/MII/RMII extended MAC port that can directly connect to a host processor, controller, FPGA, or external PHY transceiver, providing a complete Gigabit switching solution for embedded networking devices.
Shenzhen Mingjiada Electronics Co., Ltd. has long supplied genuine, in-stock Microchip KSZ9896CTXI chips at competitive prices with fast delivery, serving as a reliable component supply partner for customers in industrial control, network security, and IoT gateway applications.
Key Technical Features
Port Architecture and Interface Flexibility
The KSZ9896 employs a 6-port non-blocking line-rate switching architecture, with five ports integrating Gigabit PHYs and the sixth port serving as a configurable MAC interface supporting four modes: GMII, RGMII, MII, and RMII. The flexible digital I/O voltage design allows this MAC port to connect directly to 1.8V, 2.5V, or 3.3V host processors or FPGAs without requiring additional level-shifting circuits. The chip is equipped with a 4,096-entry forwarding table and a 256 kB frame buffer, supporting jumbo packets of up to 9,000 bytes to ensure that large packets are not lost or fragmented during store-and-forward processing.
Layer 2 Management Features
The chip provides comprehensive Layer 2 managed switching capabilities, including IEEE 802.1Q VLANs (supporting 128 active VLAN groups and the full range of 4,096 VLAN IDs), Quality of Service (QoS) (four-level priority queues based on 802.1p, IPv4 DIFFSERV, and IPv6 Traffic Class), IGMP v1/v2/v3 Snooping, and IPv6 MLD Snooping multicast filtering capabilities. In terms of security, it supports IEEE 802.1X access control based on port and MAC address, as well as Access Control List (ACL) filtering, enabling granular control over Layer 2 through Layer 4 packets.
EtherGreen™ Power Management
The KSZ9896 integrates Microchip’s proprietary EtherGreen™ power management technology, supporting multiple power-saving mechanisms: Energy Detection Power-Down (EDPD) mode when cables are disconnected, dynamic clock tree control, independent power-down of unused ports, full-chip software shutdown, and Wake-on-LAN standby mode with PME support. The chip also supports the IEEE 802.3az Energy-Efficient Ethernet (EEE) standard, which significantly reduces system power consumption in light-load network environments, meeting green and energy-efficient design requirements.
Industrial-Grade Reliability and Diagnostics
The KSZ9896 supports an industrial-grade temperature range of -40°C to +85°C, meeting the requirements for stable operation in harsh industrial environments. The built-in LinkMD® cable diagnostics feature detects cable open circuits and short circuits and measures cable length, helping field engineers quickly locate physical-layer faults. The chip also supports automatic polarity correction, automatic MDI/MDI-X crossover detection, and remote fault detection, further simplifying deployment and operations and maintenance.
Management Interfaces and Configuration
The KSZ9896 offers flexible management interface options, including a high-speed 4-wire SPI interface (up to 50 MHz), an I²C interface, an MII management (MIIM/MDC/MDIO 2-wire) interface, and in-band management via any data port. All internal registers are accessible via the SPI or I²C interfaces, while the PHY registers provide read/write channels through the MIIM interface. The chip also supports I/O pin strapping, which allows specific register bits to be configured directly via pin levels during reset, simplifying the system initialization process.
Typical Application Scenarios
With its high integration and rich management features, the KSZ9896 is suitable for a variety of network device design scenarios:
Standalone 10/100/1000 Mbps Ethernet switches: Used to build small Gigabit switching devices
VoIP infrastructure and broadband gateways: Provides a switching core for voice-and-data convergence devices
Wi-Fi access points: Wired backhaul ports for connecting wireless APs
Industrial control and automation switches: Meets the strict requirements for wide temperature ranges and reliability in industrial field applications
Security surveillance systems: Provides multi-port Gigabit connectivity for IP cameras and NVRs
