VSC8487YJU - 10GbE Ethernet Transceiver | Microchip Technology
Référence : VSC8487YJU ✓ ActifVSC8487YJU Présentation
An Ethernet transceiver is an interface IC that connects a digital communications system to a physical transmission medium. XFI and XAUI are high-speed serial interfaces commonly used to move 10GbE traffic across boards, backplanes, chassis, and equipment interconnects. A device that translates XFI to dual XAUI can bridge a narrow serial-side connection to two parallel high-speed lanes while centralizing electrical signaling, clocking, and timing functions in one component.
Key features include support for 10GbE operation, EDC and KR, dual XAUI connectivity, and IEEE 1588v2 timing compliance. These capabilities make the VSC8487 family relevant to synchronized networking equipment, Ethernet switching systems, industrial automation platforms, and test equipment that requires deterministic traffic timing. The exact electrical ratings, operating temperature, and package dimensions should be confirmed against the manufacturer datasheet before release to production.
The VSC8487 belongs to Microchip’s family of dual-channel XAUI-to-serial transceivers. The manufacturer identifies VSC8487-15 and VSC8488-15 as timing-oriented devices supporting industry-standard protocol encapsulations. This positioning places the VSC8487YJU within the broader hierarchy of Ethernet interface IC, network interface controller, data-converter semiconductor, and communication IC.
Typical applications include 10GbE switching equipment, backplane routing systems, industrial control networks, synchronized test and measurement platforms, and telecommunications infrastructure. EDC helps the receiver recover data impaired by interconnect loss, while KR support addresses known backplane signal-integrity challenges. IEEE 1588v2 compliance is especially useful when synchronized time or deterministic event ordering must be maintained across the network.
PCB implementation requires careful high-speed layout practices, including controlled impedance, short differential connections, suitable return paths, and compliance with the manufacturer’s reference design and decoupling guidance. Clocking, reference circuitry, reset behavior, and device configuration must follow the datasheet because incorrect sequencing or an unsuitable reference implementation can impair link operation even when the device itself is functioning correctly.
This page organizes the VSC8487YJU’s confirmed networking capabilities, timing features, ordering variants, and practical design implications. It also separates documented facts from parameters that require direct confirmation, helping engineers assess fit, establish pin-compatible sourcing options, and plan robust 10GbE backplane implementations before schematic release.

Applications typiques
VSC8487YJU convient pour 6 applications: 10GbE Switching Equipment, Backplane Routing Systems, Industrial Automation Networks, Synchronized Test and Measurement, Telecommunications Infrastructure, High-Speed Data Acquisition.
10GbE Switching Equipment
The VSC8487YJU fits a 10GbE switching or routing platform that must translate a single XFI serial-side connection into dual XAUI lanes. Dual-lane XAUI provides a practical high-speed board interface, while EDC supports recovery of transmitted data across a controlled interconnect. KR support is also relevant when the channel experiences recognized backplane impairment. The implementation should follow the manufacturer reference design for differential impedance, clocking, reference circuitry, and power distribution. System engineers should characterize insertion loss, return loss, skew, and jitter across the complete path rather than judging link margin from trace length alone.
Recommandé
Backplane Routing Systems
A backplane router can use the VSC8487YJU to bridge an XFI interface and dual XAUI lanes across a multilayer printed-circuit-board backplane. Its 10GbE capability targets high-bandwidth switching fabrics, while EDC and KR address signal degradation associated with long or impaired channels. Board-level success depends on controlled impedance, uninterrupted reference planes, matched differential routing, and suitable loss characteristics. Engineers should verify the channel against the device’s receiver mask and jitter requirements, including connector and via transitions, and preserve the clock and power architecture specified by Microchip.
Recommandé
Industrial Automation Networks
The VSC8487YJU is suitable for industrial automation and control equipment that exchanges 10GbE data between controllers, processing modules, and test nodes. Its single-XFI-to-dual-XAUI conversion allows a central communications device to connect with high-speed backplane logic, while EDC supports signal recovery in systems with unavoidable board-level loss. IEEE 1588v2 timing support strengthens designs requiring synchronized events or traceable timing across distributed equipment. Firmware and network architects should still define deterministic latency, clocking hierarchy, and failover behavior independently of the transceiver’s protocol capability.
Recommandé
Synchronized Test and Measurement
The VSC8487YJU can support high-throughput test and measurement platforms that move 10GbE data between instrument modules, chassis controllers, and signal-processing hardware. The XFI-to-dual-XAUI interface allows a compact internal architecture, and EDC helps maintain operation across controlled PCB channels. IEEE 1588v2 compliance is valuable where measurements or events must share a common time basis. Designers should use a low-jitter reference and clock distribution architecture, preserve recommended return paths, and validate complete end-to-end timing rather than relying only on nominal data-rate compliance.
Recommandé
Telecommunications Infrastructure
The VSC8487YJU is applicable to telecommunications aggregation and transport equipment that uses 10GbE links across internal backplanes. A single XFI port can connect to dual XAUI lanes, providing a flexible internal partitioning of high-speed traffic. EDC and KR improve resilience to recognized channel impairments, while IEEE 1588v2 support benefits timing-sensitive transport functions. PCB engineers should pay particular attention to layer transitions, connector launches, clock isolation, and power-plane return current. Any deployment requiring redundant paths or hot-swap behavior must satisfy the requirements of the complete board design, not only the transceiver.
Recommandé
High-Speed Data Acquisition
Data-acquisition systems that move continuous 10GbE streams between an FPGA-based processing section and an Ethernet-facing subsystem can use the VSC8487YJU to connect XFI and dual XAUI domains. The transceiver provides a dedicated 10GbE conversion function rather than implementing the physical link in general-purpose logic. EDC assists recovery over imperfect channels, and KR supports backplane-aware operation. The design team should confirm lane timing, reference requirements, configuration method, and exposed test points against the manufacturer documentation before fixing the PCB footprint and power network.

Notes de conception
Route XFI and XAUI as controlled-impedance differential pairs with continuous reference planes and minimized stubs. Include the effects of vias, test pads, connector launches, and layer transitions in channel simulation. Keep clock and data routing disciplined because EDC can recover from specified impairments but cannot compensate for an uncontrolled topology that violates the manufacturer’s channel requirements.
Validate insertion loss, return loss, skew, crosstalk, and jitter across the complete 10GbE channel before taping out. Compare the measured or modeled channel with Microchip’s receiver requirements, including the effects of EDC and KR. Use the manufacturer’s reference layout and de-embedding methodology to separate package and connector losses from PCB loss.
Do not infer pin assignments from the XFI and XAUI lane counts alone. Confirm power rails, reference connections, clock inputs, configuration signals, reset requirements, and exposed pads in the VSC8487 pin table and package drawing. Applying a generic 10GbE transceiver footprint can create subtle failures in startup, reference stability, configuration, or thermal performance.
