Product details
Overview
ADM6993FX-AD-T-1 from Infineon Technologies is a single-chip HDLC-to-Fast Ethernet converter IC integrating a 10/100BASE-TX PHY, 4-port Ethernet switch fabric, HDLC controller, and serial management interface (SMI). It supports MII/RMII/GPSI/HDLC port configurations, operates at 3.3 V core/io supply, and delivers full-duplex 10/100 Mbps Ethernet bridging with hardware-based address learning and aging. It is deployed in industrial telecom gateways for legacy TDM-to-Ethernet protocol translation.
For engineers reviewing the ADM6993FX-AD-T-1 datasheet, ADM6993FX-AD-T-1 pinout, ADM6993FX-AD-T-1 application, or ADM6993FX-AD-T-1 equivalent, key selection criteria include MII/RMII interface flexibility, integrated PHY compliance with IEEE 802.3u, HDLC frame handling capability, SMI register accessibility, and 128-pin PQFP thermal/mechanical suitability for carrier-grade edge equipment.
Technical Context
The ADM6993FX-AD-T-1 implements a deterministic packet-forwarding switch fabric with per-port buffer queues, broadcast storm filtering, and auto-MDIX support. Its HDLC controller handles synchronous bit-oriented framing with CRC-16 generation/checking and configurable flag detection.
It features dual PHY interface modes: Port 0/1 as 10/100BASE-TX twisted-pair transceivers with auto-negotiation, and Port 2 configurable as MII (17-pin), RMII (7-pin), GPSI (7-pin), or HDLC (4-pin) - enabling interoperability with legacy serial controllers and modern MACs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDLC-to-Ethernet conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6060 | Dedicated 4-port switch only; no integrated HDLC controller or PHY - requires external HDLC ASIC and PHY | Suitable for designs where HDLC processing is offloaded to an FPGA or separate controller | Select when system already includes HDLC logic and only Ethernet switching is needed. |
| TI DP83848C | Standalone 10/100BASE-TX PHY only; no switch fabric or HDLC engine - must pair with external MAC and HDLC processor | Used in custom HDLC-to-Ethernet bridges built around microcontrollers or FPGAs | Select when maximum design flexibility and independent firmware control over HDLC framing are required. |
Compared with Marvell 88E6060 and TI DP83848C, the ADM6993FX-AD-T-1 uniquely integrates all three functional blocks - HDLC controller, switch fabric, and PHY - reducing PCB area by ~40%, eliminating inter-chip timing skew, and simplifying qualification for EN 55032/EN 55024 emissions compliance.

FAQ
Does ADM6993FX-AD-T-1 support IEEE 1588 Precision Time Protocol (PTP)?
No. The ADM6993FX-AD-T-1 does not implement PTP timestamping or hardware-assisted synchronization. Its timing architecture is optimized for deterministic HDLC frame forwarding and Ethernet MAC-layer bridging, not sub-microsecond clock synchronization. PTP functionality must be added externally via a companion MCU or FPGA.
Can Port 2 operate simultaneously in MII and HDLC modes?
No. Port 2 is configured at power-on reset via strapping pins (MODE2:0) to operate exclusively in one mode: MII, RMII, GPSI, or HDLC. Mode selection is static and cannot be changed dynamically during runtime without cycling power or asserting hardware reset.
What is the maximum HDLC frame length supported?
The ADM6993FX-AD-T-1 supports HDLC frames up to 1518 bytes, matching standard Ethernet MTU size. Frame boundaries are detected via flag sequences (0x7E), and the internal FIFO buffers accommodate full-size frames with CRC-16 appended, verified per Section 3.6 of the Rev 1.11 datasheet.
Is the 128-pin PQFP RoHS-compliant?
Yes. Per Revision 1.11 (Nov. 2005) of the datasheet, the ADM6993FX-AD-T-1 is manufactured in a "Green package" meeting RoHS Directive 2002/95/EC requirements, with lead-free solderability and halogen-free molding compound confirmed in Section 6 and the title page footnote.
