KSZ9896CTXC-TR

Controllers Overview

The KSZ9896CTXC-TR is a six-port Gigabit Ethernet managed switch IC manufactured by 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. Electrical specifications include a supply voltage range of 1.8 V to 3.465 V and a maximum power consumption of 750 mA. It operates within a commercial temperature range of 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 LinkMD cable diagnostics and fast link-up capabilities.
• Supports advanced Layer 2 management including IEEE 802.1Q VLANs, QoS prioritization, and IEEE 802.1X access control.
• Provides flexible host connectivity via SPI, I2C, MIIM, or in-band management through any data port.

Controllers Applications

• Stand-alone 10/100/1000Mbps Ethernet switches
• VoIP infrastructure switches
• Broadband gateways and firewalls
• Wi-Fi access points
• Security and surveillance systems

Controllers Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing components. Confirm that the device revision matches the required silicon version for compatibility with existing designs. Ensure compliance with RoHS directives as specified in the manufacturer documentation before finalizing procurement orders.

Controllers Selection Notes

Select this component for designs requiring integrated Gigabit PHYs without external transceivers. The single MAC port allows direct connection to host processors or FPGAs using standard interfaces like RGMII. Consider the 128-pin TQFP-EP package size and thermal requirements when planning the PCB layout and heat dissipation strategy.

Controllers Part Context

This part belongs to the KSZ9896 family of highly integrated Ethernet switches. The 'C' designation typically refers to the specific silicon revision or feature set variant within the series. The 'TXC' indicates the 128-pin TQFP-EP package type, while '-TR' specifies the reel packaging format for automated assembly processes.

Controllers Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Verify pin-to-pin compatibility and register-level functionality if replacing with other members of the KSZ9896 family or newer revisions.
