ADM6992FX-AB-T-1

Overview

The ADM6992FX-AB-T-1 is a single-chip Fiber to Fast Ethernet converter integrating two 10/100 Mbps MDIX TX/FX transceivers with a two-port 10/100M Ethernet L2 switch controller. It supports 10Base-T, 100Base-TX, and 100Base-FX media types via digital circuitry and high-speed A/D conversion. The device includes an embedded OAM engine compliant with TS1000 for CPE and CO functions, enabling remote control via OAM frames. It features a built-in 6Kx64bit SRAM data buffer and supports up to 1k of Unicast MAC addresses using a 4-way associative hashing table. The component operates on a 1.8 V or 3.3 V power supply and utilizes a 128-pin PQFP package.

Feature Summary

• Integrates a two-port 10/100M Ethernet L2 switch controller with dual 10/100 Mbps PHY transceivers.
• Supports TX FX Converter modes with Link Pass Through (LPT) functionality.
• Includes an embedded OAM engine compliant with TS1000 standards for CPE and CO applications.
• Provides hardware bandwidth control for both ingress and egress traffic.

Applications

• Fiber-to-Ethernet media converters
• FTTH (Fiber to the Home) Customer Premises Equipment (CPE)
• FTTH Central Office (CO) implementations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and environmental compliance status. Confirm that the 128-pin PQFP package dimensions match the target PCB footprint requirements. Ensure the design accounts for the required 1.8 V and 3.3 V power supply rails as specified in the electrical characteristics section of the datasheet.

Selection Notes

Select this component when a combined switching and media conversion function is required within a single integrated circuit. It is suitable for designs needing TS1000 OAM compliance for remote management without external controllers. Consider the 128-pin PQFP package constraints and the need for external EEPROM or SMI interface configuration based on system complexity and cost targets.

Part Context

This part belongs to the NINJA F/FX family, which integrates PHY and switching capabilities. The 'FX' designation indicates support for fiber optic interfaces alongside twisted pair ports. The 'green' package version denotes environmentally friendly manufacturing processes. This series was designed to simplify network edge deployments by consolidating multiple discrete components into one chip.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify cross-reference availability through official Infineon channels if direct replacement is necessary due to obsolescence.
