ADM6992CX-AB-T-1

Overview

The ADM6992CX-AB-T-1 is a single-chip Ethernet converter and switch controller integrating two 10/100 Mbps MDIX TX/FX transceivers with a two-port L2 switch. It supports 10Base-T, 100Base-TX, and 100Base-FX media via IEEE 802.3 standards. The device features a built-in 6Kx64-bit SRAM buffer and handles packet lengths up to 9216 bytes. It operates on 1.8 V and 3.3 V power supplies within a 64-pin LQFP package.

Feature Summary

• Integrates two-port 10/100M switch controller with dual PHY transceivers for twisted pair and fiber interfaces.
• Supports store-and-forward, modified cut-through, and fast cut-through frame forwarding modes.
• Provides hardware bandwidth control for ingress and egress traffic along with 802.3x flow control.
• Enables packet classification and filtering based on TCP/UDP ports, IP protocol IDs, and Ethernet types.

Applications

• Fiber-to-Ethernet media converters
• Industrial Ethernet network bridging
• Two-port Ethernet switching nodes

Procurement Notes

Verify the component status as the source datasheet indicates this product line may be discontinued or limited. Confirm the specific ordering suffix matches the required environmental packaging and interface configuration before procurement.

Selection Notes

Select this component when a combined PHY and L2 switch solution is required for compact designs. Ensure the system design accommodates the 64-pin LQFP footprint and provides separate 1.8 V and 3.3 V power domains for optimal operation.

Part Context

This part belongs to the Ninja C/CX family of communication controllers. It serves as a bridge between copper-based Ethernet networks and fiber optic links, consolidating physical layer and data link layer functions into a single integrated circuit.

Replacement Considerations

Consult official Infineon documentation for verified substitute part numbers. Cross-referencing with similar Ninja series components requires validation of pin compatibility and register mapping.
