MPN: LAN9513-JZX ✓ NakahandaLAN9513-JZX Ulas
A USB interface controller is a semiconductor that bridges a host controller or host computer with peripheral devices, while an Ethernet controller combines media-access control with physical-layer signaling. The LAN9513 belongs to the interface-controller and network-interface hierarchy, integrating USB hub, Ethernet, test-access-port, and EEPROM-control functions to reduce external circuitry in embedded USB-to-Ethernet products.
The LAN9513-JZX provides three integrated downstream USB 2.0 PHYs, one integrated upstream USB 2.0 PHY, a 10/100 Ethernet PHY, and a 10/100 Ethernet controller. According to the manufacturer data sheet, the Ethernet section complies with IEEE 802.3 and IEEE 802.3u and supports 10BASE-T and 100BASE-TX links. It also supports full- and half-duplex operation with flow control, preamble generation and removal, and automatic 32-bit CRC generation and checking.
The integrated TAP controller and EEPROM controller add system-management functions around the dual USB and Ethernet interfaces. This consolidation is valuable in embedded systems, desktop and notebook computers, printers, game consoles, and docking stations where designers need an economical and power-efficient USB-to-Ethernet or multi-port USB connectivity solution without assembling separate hub and Ethernet components.
Typical implementation places the LAN9513-JZX between an upstream USB 2.0 host and an RJ45-based 10/100 Ethernet network. Its three downstream USB PHYs support hub ports while the integrated Ethernet MAC and PHY provide a network interface over twisted-pair cabling. The manufacturer documentation identifies embedded systems, PCs, notebooks, printers, consoles, and docking stations as representative applications.
PCB implementation should follow the LAN9512/LAN9513/LAN9514 layout guidance, with particular attention to controlled-impedance USB and Ethernet routing, solid ground planes, decoupling near supply pins, isolation between sensitive analog network paths and digital switching paths, and unobstructed copper beneath the exposed pad. The LAN9513 reference design and Microchip application note AN 19.20 provide implementation-specific guidance.
This product summary consolidates verified distributor pricing, package and electrical characteristics, source links, application guidance, and a drop-in replacement assessment. It distinguishes confirmed identical ratings from exact feature or pin differences that still require verification against the manufacturer data sheet before substitution.

Tipikal na mga Gamit
LAN9513-JZX ay nararapat para sa 6 aplikasyons: USB-to-Ethernet Adapter, Embedded USB Networking, Desktop USB Connectivity Hub, Industrial Printer Connectivity, Game Console and Set-Top Accessory, Networked Test and Measurement Instrument.
USB-to-Ethernet Adapter
The LAN9513-JZX is suitable for a compact USB-to-Ethernet adapter because it combines one upstream Hi-Speed USB 2.0 interface with an integrated 10/100 Ethernet MAC, PHY, and 10/100 controller. A 3.3 V operating supply and 64-QFN package support dense adapter designs, while the integrated PHY reduces the need for separate Ethernet transceiver circuitry. The Ethernet side supports 10BASE-T and 100BASE-TX, full- and half-duplex operation, flow control, preamble handling, and automatic 32-bit CRC processing. Design the board around Microchip's LAN9513 reference schematic and AN 19.20 layout guidance, including controlled-impedance USB routing and an Ethernet magnetics section.

Embedded USB Networking
The LAN9513-JZX fits embedded systems that need both USB peripheral connectivity and wired network access without implementing separate hub and Ethernet controller devices. Its three downstream USB 2.0 PHYs allow one upstream host connection to feed multiple USB peripherals, while the integrated 10/100 Ethernet controller provides a second data path over twisted-pair networking. This consolidation can reduce board area, firmware coordination, and external PHY count. Integration does not remove Ethernet magnetics or layout requirements: the implementation must preserve high-speed USB signal integrity, provide appropriate Ethernet termination and isolation, and observe the exposed-pad thermal and grounding requirements.
Inirekomenda
Desktop USB Connectivity Hub
The three downstream USB 2.0 PHYs in the LAN9513-JZX support compact desktop or notebook docking designs where several USB peripherals share one upstream host port. The same device also provides 10/100 Ethernet connectivity, allowing one controller to manage USB expansion and wired networking. This is particularly useful in legacy and industrial peripherals that lack a native high-speed network interface. The design trade-off is shared internal resources and USB power-delivery requirements: each exposed port still needs compliant power switching and protection, while the host must correctly enumerate all downstream devices.
Inirekomenda
Industrial Printer Connectivity
Printers and embedded print engines can use the LAN9513-JZX to combine a host USB connection with a 10/100 Ethernet network interface. The controller supports both 10BASE-T and 100BASE-TX, making it appropriate for copper networks operating below the device's 100 Mb/s Ethernet limit. The three downstream USB PHYs can support peripherals such as status displays, scanners, or local configuration devices without requiring a separate hub IC. Firmware must configure the USB hub and Ethernet controller coherently, and the PCB should keep Ethernet magnetics and USB routing areas separated from noisy power-conversion stages.
Inirekomenda
Game Console and Set-Top Accessory
The LAN9513-JZX addresses accessory and docking requirements in game consoles and set-top equipment by combining an upstream USB 2.0 connection, three downstream USB ports, and 10/100 Ethernet. A console can use the hub function for controllers or storage accessories while the Ethernet controller provides wired service or local-network connectivity. The 9 mm × 9 mm QFN package supports compact boards, although its exposed pad requires a properly designed thermal and electrical ground connection. Host firmware must provide stable USB enumeration, port-power management, and network-driver integration, while the PCB follows controlled-impedance routing for both USB and Ethernet.
Inirekomenda
Networked Test and Measurement Instrument
The LAN9513-JZX can provide USB connectivity and 10/100 Ethernet in compact test and measurement instruments that need to exchange data with a host and a local network. The Ethernet controller supports full- and half-duplex modes with flow control, which is useful for instrument-management traffic, while the three downstream USB PHYs can connect service interfaces, storage, or front-panel peripherals. Flow control and CRC processing reduce host-side protocol complexity. System integrators should treat the 3.3 V supply as a clean rail, isolate Ethernet magnetics from analog measurement circuitry, and use the manufacturer reference design as the baseline for high-speed signal routing.

Talaan ng Disenyo
Follow Microchip application note AN 19.20 and the LAN9513 reference schematic rather than improvising the high-speed layout. Route USB and Ethernet differential pairs over continuous reference planes, minimize stubs and test-point discontinuities, and maintain the geometry specified by the data sheet. Keep switching power stages and their high-current loops away from Ethernet magnetics and USB pairs, while providing a continuous ground reference beneath the exposed pad.
Use a clean 3.3 V rail and place the data-sheet-specified decoupling capacitors immediately beside their associated supply pins. Separate USB port-power switching from the logic rail so hub current transients do not pull down the LAN9513 core supply. Verify the total USB port-current budget, port-power protection, and supply sequencing against the host requirements. Because no detailed regulator options are specified in the verified data, do not assume that an adjacent switching converter can meet USB ripple limits without measurement.
Do not treat a matching 64-QFN outline as proof of drop-in compatibility. Before substituting LAN9513I-JZX, LAN9514-JZX-TR, or LAN9514I-JZX, compare every ball or pin assignment, exposed-pad connection, strap option, EEPROM interface, crystal or clock requirement, USB transceiver behavior, and Ethernet support in the applicable manufacturer data sheet. A PCB can fit physically while still failing because a configuration pin, power sequence, or peripheral function differs.
The 10/100 Ethernet rating does not make this a gigabit device. Do not select it for 1000BASE-T requirements, and do not assume that all USB hub power, enumeration, or over-current requirements disappear because the PHY and controller are integrated. External port-power switches, protection components, magnetics, connectors, and clock or EEPROM components may still be required according to the reference design and individual system requirements.
