The ACMD-7605 is a half-duplex 10Base-T Ethernet Media Access Control (MAC) + Physical Layer (PHY) transceiver. This device integrates both the MAC and PHY functions to provide a complete Ethernet solution. It is designed to interface with standard Ethernet controllers via a Media Independent Interface (MII) or a Reduced Media Independent Interface (RMII).

Applications:

• Embedded Ethernet applications
• Industrial control systems
• Networked appliances
• Point-of-sale terminals
• Ethernet-enabled instrumentation

Features:

• Integrated MAC and PHY for 10Base-T Ethernet
• Supports half-duplex operation
• MII/RMII interface
• Low power consumption
• Auto-negotiation support
• Loopback test mode
• Built-in filtering to reduce external component count
• IEEE 802.3 compliant

Benefits:

• Simplified Ethernet connectivity for embedded systems
• Reduced board space and component count due to integration
• Lower power consumption, suitable for battery-powered devices
• Easy integration with existing Ethernet controllers
• Improved system reliability due to integrated solution
• Cost-effective Ethernet solution

Additional Details:

The ACMD-7605 operates from a 3.3V power supply. It features a built-in transmit and receive filter to reduce the need for external components. It has a loopback test mode which makes it simple to test the functionality of the transceiver. The device is available in a small form factor package which helps in miniaturized designs.

The MAC portion of the ACMD-7605 handles all of the functions of an Ethernet MAC including preamble generation, address detection, frame check sequence generation and checking, and collision detection. The PHY portion handles all of the analog functions of transmitting and receiving Ethernet signals over twisted pair cabling. It includes features such as adaptive equalization and baseline wander correction.
