    BCM89810A2AMLGT Typical application Circuitry


    BCM89810A2AMLGT: This Broadcom chip is a single-port BroadR-Reach automotive Ethernet transceiver. The BroadR-Reach technology enables Ethernet over unshielded twisted-pair wiring, typically in automotive applications.


    The BCM89810A2AMLGT serves to provide automotive Ethernet connectivity. It offers low-power, robust communication, and meets the automotive qualification standards.

    Application Scenarios:

    1. In-vehicle infotainment systems. 

    2. Advanced Driver Assistance Systems (ADAS). 

    3. Vehicle-to-X communication. 

    4. Gateway and zonal architecture communication within a vehicle.

    Parameter Features:

    - Connectivity: BroadR-Reach Ethernet over unshielded twisted-pair. 

    - Data Rate: Typically 100 Mbps. 

    - Temperature Range: Automotive-grade temperature tolerances.

     - Compliance: Meets automotive EMI requirements. 

    - Power Mode: Low-power modes for efficient consumption.

    Application in In-vehicle Infotainment Systems:

    Let's consider using the BCM89810A2AMLGT in an in-vehicle infotainment system:

    1. Power Supply: Pin VCC should be connected to a 3.3V automotive-grade power supply. Capacitors should be placed as close to the pin as feasible to provide good decoupling.

    2. Ethernet Connectivity: The TX (transmit) and RX (receive) pins are vital. For the BCM89810A2AMLGT, these would interface with the unshielded twisted-pair cables leading to the infotainment system's head unit or display.

    3. MDI Interface: This interface connects the chip to the physical media (twisted-pair cable). Ensure that the MDI pins (MDI_P and MDI_N for positive and negative signals) are correctly connected.

    4. Management Interface: Use the MDIO (Management Data Input/Output) and MDC (Management Data Clock) pins to interface with a controller or MCU for configuring and monitoring the transceiver's operations.

    5. Oscillator Input: Connect a 25MHz crystal oscillator to the XTAL_IN and XTAL_OUT pins to serve as the chip's clock source.

    Design Considerations:

    1. EMI and EMC: Given that this is for automotive applications, ensure the design meets stringent Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) requirements.

    2. Robustness: The automotive environment is harsh. Considerations for vibrations, temperature fluctuations, and humidity are essential.

    3. Power Management: Vehicles rely on battery power, so designs should minimize power consumption whenever possible. Look into the BCM89810A2AMLGT's low-power modes and ensure they're properly utilized.

    4. Cable Lengths: Even though the BroadR-Reach technology is robust, maintain the shortest possible cable lengths to prevent potential signal degradation.

    5. Protection: Implement protection circuits to safeguard against possible electrical hazards, like voltage spikes during engine cranks.

    For optimal results with the BCM89810A2AMLGT in any automotive application, designers should be well-versed with its datasheet, Broadcom's guidelines, and the specific requirements of the automotive sector.
