Product details
Overview
ADM6993X-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 access gateways for T1/E1-to-Ethernet protocol translation.
For engineers reviewing the ADM6993X-AD-T-1 datasheet, ADM6993X-AD-T-1 pinout, ADM6993X-AD-T-1 application, or ADM6993X-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 ADM6993X-AD-T-1 implements a deterministic Layer 2 switching engine with 1 K MAC address table depth, automatic aging timeout configurable between 5–400 seconds, and per-port broadcast storm filtering. Its HDLC controller supports transparent bit-oriented framing with CRC-16/CCITT checksum generation and verification.
It integrates a fully compliant 10/100BASE-TX PHY with Auto-Negotiation (IEEE 802.3u), Auto-MDIX, and half/full-duplex flow control. The device uses a shared memory architecture with 16 KB internal packet buffer and supports both EEPROM-based configuration and real-time SMI register access for runtime reconfiguration.

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 |
|---|---|---|---|
| Intel 82559ER | PCI-based Ethernet controller without integrated HDLC; requires external HDLC ASIC or FPGA logic | Targeted at PC-based gateway platforms with PCI bus; lacks native TDM interface support | Select only when host processor handles HDLC framing and system architecture mandates PCI connectivity |
| Microchip LAN9252 | 2-port EtherCAT slave controller with SPI/parallel host interface; no HDLC engine or MII PHY | Designed for industrial motion control networks-not suitable for T1/E1 protocol translation | Reject for HDLC-to-Ethernet use cases; applicable only in EtherCAT-specific deterministic automation systems |
Compared with Intel 82559ER and Microchip LAN9252, the ADM6993X-AD-T-1 uniquely combines HDLC controller, 10/100 PHY, and switch fabric in one package-enabling single-chip TDM-to-Ethernet bridging without host CPU framing overhead or external glue logic.

FAQ
Does ADM6993X-AD-T-1 support JTAG debugging or boundary scan?
No. The ADM6993X-AD-T-1 does not include JTAG TAP controller or IEEE 1149.1 boundary-scan support. Debugging and register inspection rely exclusively on the Serial Management Interface (SMI) and EEPROM configuration interface per sections 3.5 and 4.2 of the Rev 1.11 datasheet.
Can the HDLC controller operate in asynchronous mode with start/stop bits?
No. The HDLC controller is strictly synchronous and bit-oriented. It requires continuous clocking (HDLC_CLK input) and supports only flag-delimited frames with zero-bit stuffing and CRC-16. Asynchronous protocols like RS-232 or UART framing are not supported.
What is the maximum HDLC data rate supported by ADM6993X-AD-T-1?
The HDLC interface supports serial clock frequencies up to 8 MHz, enabling raw HDLC data rates of up to 8 Mbps. This accommodates full-rate E1 (2.048 Mbps) and fractional E1 channels with headroom for overhead and guard bands.
Is the 128-pin PQFP package RoHS-compliant per the 2005 datasheet revision?
Yes. Per Revision 1.11 (Nov. 2005), the ADM6993X-AD-T-1 "Green package" designation confirms lead-free terminations and halogen-free molding compound, meeting EU RoHS Directive 2002/95/EC requirements effective July 2006.
