KSZ9896CTXC

Controllers Overview

The KSZ9896CTXC is a six-port Gigabit Ethernet managed switch IC from Microchip Technology. It integrates five 10/100/1000BASE-T PHY transceivers and one configurable MAC port supporting GMII, RGMII, MII, or RMII interfaces. The device features a non-blocking wire-speed switching fabric with a 256 kByte frame buffer and a 4096-entry forwarding table. It supports IEEE 802.3 standards including 10BASE-Te, 100BASE-TX, and 1000BASE-T. Operating voltage ranges from 1.8 V to 3.465 V, with a maximum power consumption of 750 mA. The component operates within commercial temperatures (0°C to +70°C) and is housed in a 128-pin TQFP-EP package.

Controllers Feature Summary

• Integrates five 10/100/1000BASE-T PHYs with on-chip termination resistors and LinkMD cable diagnostics.
• Provides full VLAN support for 128 active groups and QoS prioritization via 802.1p classification.
• Supports advanced security through IEEE 802.1X access control and ACL filtering.
• Offers flexible management via SPI, I2C, MIIM, and in-band protocols.

Controllers Applications

• VoIP infrastructure switches
• Broadband gateways and firewalls
• Wi-Fi access points
• Integrated DSL/cable modems
• Security and surveillance systems

Controllers Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm the commercial temperature range rating. Ensure the 128-pin TQFP-EP package dimensions match the design constraints. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into the manufacturing process.

Controllers Selection Notes

Select this component when a compact solution is required for multi-port Gigabit connectivity without external PHYs. The integrated MAC port allows direct connection to host processors or FPGAs. Consider the power management features, such as Energy Detect and Wake-on-LAN, if system energy efficiency is a priority.

Controllers Part Context

This part belongs to the KSZ9896 series of Layer 2 managed switches. The 'C' suffix typically denotes the commercial temperature grade variant, distinct from industrial versions. It serves as a high-density networking solution designed to offload processing tasks from the main host controller.

Controllers Replacement Considerations

Consult the manufacturer's product selector for alternative packages or temperature grades within the same family. Verify pin compatibility and register mapping if substituting with other members of the KSZ9896 series.
