    DP83867IRRGZR Typical application Circuitry


    The DP83867IRRGZR is a high-immunity, small form-factor, robust Ethernet physical layer transceiver from Texas Instruments. It offers all physical layer capabilities required for data transmission and reception across both common twisted-pair cables and twisted-pair media interfaces.

    Here's an in-depth guide for creating accurate connections to the DP83867IRRGZR's specific pins:

    1. Power Connections:The DP83867IRRGZR operates with two power supply voltages - a 3.3V supply voltage connected to RADIO (pin 32), and a supply voltage ranging from 1.14V to 3.6V applied to EDDA (pin 9).

    2. Ethernet Interface:Connect the differential pairs for Ethernet data - RX+ (pin 21), RX- (pin 20), TX+ (pin 19), and TX- (pin 18) - to your Ethernet transformer for data transmission and reception.

    3. MAC Interface:For MAC interfaces, the DP83867IRRGZR can be configured to several modes. If using Reduced Gigabit Media Independent Interface (REMIX) mode, connect RXD[3:0], RX_CTV, TED[3:0], and TX_CTL pins to your Ethernet MAC. For other modes, check the datasheet for appropriate pin connections.

    4. Reference Clock:Connect a 25 MHz crystal oscillator between the ITAL_IN (pin 24) and ITAL_OUT (pin 23) pins of the DP83867IRRGZR.

    5. Reset Pin:Utilize the RESET_N (pin 6) to reset the DP83867IRRGZR by providing an active low signal.

    6. LED Indicators:You can connect LEDs to LED_0 (pin 2) and LED_1 (pin 3) to indicate link status and activity.

    7. Strap Pins:The DP83867IRRGZR offers strap pins such as SEMI_RATE_ADAPT, ELK_OUT32M, MDC/MDI_ADD_SEL, HAD[0], and HAD[1] that can be configured high or low at power-up for desired settings.

    8. Decoupling Capacitors:To help reduce power supply noise, place decoupling capacitors as close as feasible to each power supply pin.

    Bear in mind, that this is a rudimentary outline for creating connections to the DP83867IRRGZR. The specific necessities of your application may demand additional connections. For comprehensive and precise instructions, it is always recommended to refer back to the most recent datasheet and reference manual.
