    LAN9514I-JZX Typical application Circuitry


    The LAN9514I-JZX, made by Microchip, is a Hi-Speed USB 2.0 to Ethernet controller, which comprises a four-port USB 2.0 hub along with a 10/100 Ethernet controller. It offers an efficient way to interface networking and I/O to your system through USB. Below is a guideline on how to integrate the LAN9514I-JZX into a circuit, with a focus on the specific pins.

    1. Power Supply (VDD33IO, VDD33A, GND): The power supply for this IC should be connected to the VDD33IO (Pins 20, 40, 60, 80, 100, and 120), and VDD33A (Pins 22, 42, 62, 82, 102, and 122) pins. They ought to be given a 3.3V power source. It is necessary to connect the GND pins to the ground. As per best practices, decoupling capacitors should be employed close to these pins to stabilize the power supply.

    2. USB Ports (DPI, DMX): The LAN9514I-JZX offers four downstream USB ports. The DPI and DMX (where x varies from 1 to 4) pins, i.e., D+(Pins 44-45, 56-57, 72-73, 96-97) and D- (Pins 46-47, 54-55, 74-75, 98-99) should be connected to the data lines of your USB devices.

    3. Ethernet Interface (Tax, Rex): For the Ethernet interface, the TX+/- (Pins 25 and 26) and RX+/- (Pins 27 and 28) should be connected to the Ethernet transceiver.

    4. Reset (reset): The reset pin, reset (Pin 12), is active low and should be tied to a reset circuit in your design. This pin resets the device.

    5. Crystal Oscillator (XTAL1, XTAL2): A 25 MHz crystal oscillator is connected to XTAL1 (Pin 6) and XTAL2 (Pin 7) to serve as the clock input to the device.

    6. LED Indicators (Led): The LAN9514I-JZX also features LED outputs (LED0-LED3) that can be connected to LED indicators to show link status and activity for each USB port.

    In conclusion, the LAN9514I-JZX is an efficient solution to integrate networking and I/O functionality into a system through USB. However, always refer to the data sheet for specific information and design considerations. Be mindful of the layout and routing, especially for power supply decoupling and high-speed signal paths, to make sure your design functions as expected.
