常見問題解答
What is DP83849IDVS/NOPB?
The DP83849IDVS/NOPB is a low-power, IEEE 1588-enabled, 10/100 Mbps Ethernet physical layer transceiver designed by Texas Instruments. It is ideal for networking applications requiring reliable and efficient Ethernet connectivity, such as industrial automation, automotive networking, and IoT devices.
How Does DP83849IDVS/NOPB Work?
The DP83849IDVS/NOPB works by providing the physical layer interface between the Ethernet MAC (Media Access Control) layer and the twisted-pair cable. It supports auto negotiation for seamless 10/100 Mbps operation and features advanced power management modes to minimize power consumption. Additionally, it integrates IEEE 1588 precision time protocol support for applications requiring accurate time synchronization.
How Many Pins does DP83849IDVS/NOPB have and What are the Functions of the Pinout Configuration?
The DP83849IDVS/NOPB is housed in a 36-pin package. The pinout configuration includes:
- TXD[3:0]: Transmit data signals.
- RXD[3:0]: Receive data signals.
- RXC/RXER: Receive clock or receive error signal.
- COL/LED[3:0]: Collision or LED control signals.
- MDIO: Management data input/output for configuration and status monitoring.
- RESET: Reset input pin.
- INTRQ: Interrupt request output pin.
- AVDD, DVDD: Power supply pins.
- REFCLK, CLK125: Reference clock and 125 MHz clock input signals.
- XTAL1, XTAL2: Crystal oscillator input and output signals.
What are the Pros and Cons of DP83849IDVS/NOPB?
Pros:
- Low Power Consumption: Operates with low power, suitable for energy-efficient designs.
- IEEE 1588 Support: Integrates precision time protocol support for accurate time synchronization applications.
- Auto Negotiation: Supports automatic configuration for seamless 10/100 Mbps operation.
- Advanced Power Management: Features power-saving modes for reduced energy consumption.
- Robust Ethernet Connectivity: Provides reliable physical layer interface for Ethernet communication.
Cons:
- Complexity: Integrated IEEE 1588 support may require additional configuration and expertise in time synchronization applications.
- Package Size: The 36-pin package may require additional board space in compact designs.
- External Components: May require external magnetics and termination components for complete Ethernet connectivity.
Are There Any Equivalents/Alternatives to DP83849IDVS/NOPB for Recommendation?
- The DP83822I from Texas Instruments is a similar low-power Ethernet transceiver with reduced pin count.
- Alternatives to the DP83849IDVS/NOPB include the KSZ8081 from Microchip Technology and the LAN8710A from Microchip Technology.
