VSC8490EV - Dual-Port 10G Ethernet Eval Board | Microchip
N.º de pieza: VSC8490EV ✓ ActivoVSC8490EV Descripción general
A 10G Ethernet transceiver is a high-speed communications semiconductor that converts between serial network interfaces and parallel or widebus internal data paths. Within the broader hierarchy, the VSC8490 belongs to Ethernet physical-layer interfaces, interface controllers, network semiconductors, and integrated circuits. Its dual-port architecture allows two high-speed links to be evaluated on one hardware platform, which is useful when developing backplane equipment or optical module host cards.
The VSC8490 family description specifically identifies XFI/SFI inputs and (R)XAUI outputs. XFI and SFI are serial interface formats commonly used between Ethernet line cards and optical modules, while (R)XAUI provides a widebus electrical interconnect suitable for backplane and chassis-oriented designs. The same source identifies compatibility work for SFP+ SR, LR, ER, and ZR fiber applications and describes EDC compensation as part of the family feature set.
The family also provides IEEE 1588 timing support and MACsec functionality. IEEE 1588 capability is relevant to systems requiring synchronized network timing, while MACsec is the IEEE security mechanism for protecting Ethernet frames against unauthorized injection and eavesdropping. These capabilities make the evaluation platform relevant to precise timing, secure networking, line-card development, and optical transport prototyping.
VSC8490EV is suitable for laboratory evaluation of dual-port 10G Ethernet links, optical module host cards, electrical backplane prototypes, SFP+ interface development, and secure network equipment. Engineers should confirm the board’s physical connectors, supported electrical standards, reference clock requirements, power input, operating temperature, and programming interface against the complete manufacturer documentation before using it in a production design.
This page consolidates the verified manufacturer description, distributor inventory information, family-level interface details, sourcing links, and explicit engineering gaps for the VSC8490EV. It distinguishes documented facts from unavailable specifications so procurement and hardware teams can assess the evaluation board without mistaking unreported board details for guaranteed capabilities.

Aplicaciones típicas

Dual-Port 10G Ethernet Link Evaluation
The VSC8490EV provides a platform for evaluating the VSC8490’s dual-port 10G Ethernet operation before a custom line card is released. According to the manufacturer product-page result, the VSC8490 family includes XFI/SFI host-side interfaces and (R)XAUI widebus connectivity, allowing engineers to characterize both sides of a high-speed link. The dual-port arrangement also supports side-by-side testing of two 10 Gb/s paths. Exact test-point labels, clocks, and configuration procedures are not included in the supplied data, so engineers should follow the manufacturer evaluation documentation before interpreting board measurements.
Recomendado
Electrical Backplane Prototype
The VSC8490EV is relevant to electrical-backplane development because the VSC8490 is explicitly positioned for backplane applications and exposes a (R)XAUI widebus interface. Engineers can use the evaluation platform to investigate link behavior across intended connector and trace configurations before committing to production routing. The available verified information does not specify maximum reach, insertion-loss tolerance, connector type, or equalization presets for the evaluation board. Those channel requirements must therefore be established from the complete VSC8490 documentation and the target backplane architecture.
Recomendado
Optical Module Host-Card Development
The VSC8490EV supports optical module host-card prototyping around the VSC8490’s XFI/SFI-side connectivity and family support for SFP+ SR, LR, ER, and ZR application work. This combination allows developers to evaluate the electrical behavior between a host line card and an optical module interface before integrating the transceiver into a custom PCB. The supplied data does not identify the physical SFP+ cage arrangement or optical-module operating limits of the board, so those details require confirmation before inserting an optical module or performing compliance testing.
Recomendado
IEEE 1588 Timing-System Validation
The VSC8490 family’s IEEE 1588 capability makes the VSC8490EV applicable to laboratory validation of synchronized Ethernet timing behavior. Engineers can use the dual-port evaluation setup to observe how the transceiver family interacts with timing-aware line-card software and external synchronization circuitry. Because the verified records do not state supported PTP profiles, clocking requirements, timestamp resolution, or board test points, those characteristics should be checked against the manufacturer user guide. This prevents assumptions that generic Ethernet timing support automatically satisfies a specific precision profile.
Recomendado
MACsec Secure-Network Prototype
The VSC8490EV can support early MACsec validation because MACsec is identified within the VSC8490 transceiver family. This is useful for security-focused 10G Ethernet prototypes where frame confidentiality and integrity must be assessed before production hardware is released. Two ports can support controlled traffic paths through the evaluation environment. The supplied evidence does not specify cipher-suite support, key-management interfaces, line rate, or whether MACsec processing is enabled by default, so engineers must verify those features and software requirements in the authoritative Microchip documentation.
Recomendado
SFP+ Interface Compatibility Testing
The VSC8490EV is useful for SFP+ interface development because the VSC8490 family information identifies work covering SR, LR, ER, and ZR fiber applications. A dual-port platform can support controlled comparisons between different optical reach configurations while preserving the same XFI/SFI host-side architecture. The available records do not list the supported module vendors, management behavior, or the board’s complete optical-module test coverage. Compatibility claims should therefore be validated against the manufacturer’s supported-module list, and production designs should retain configuration control for both board firmware and optical-module selection.

Notas de diseño
Do not treat the VSC8490 transceiver’s published family capabilities as automatically complete specifications for the VSC8490EV evaluation board. The verified records establish the VSC8490’s dual-port 10G Ethernet, XFI/SFI, (R)XAUI, IEEE 1588, MACsec, EDC, and backplane or optical host-card positioning, but they do not disclose the evaluation board’s connector pinout, power rails, reference clocks, or programming interface. Obtain the current board schematic and user guide before making wiring or firmware assumptions.
Plan high-speed validation around the intended XFI/SFI and (R)XAUI channels rather than treating all board paths as equivalent Ethernet links. Use the manufacturer’s recommended module, cable, connector, and termination configuration so test results reflect the supported channel. Compare eye quality, jitter, and error behavior across both ports, and account for EDC configuration when changing board loads or cabling. No channel-length or insertion-loss limit was supplied, so neither should be inferred from the 10 Gb/s headline specification.
Verify the board’s required supply voltages, sequencing, and current limits from the complete documentation before connecting test equipment. The VSC8490EV is an evaluation platform and is likely to include more than the transceiver’s core power requirements, but the supplied records contain no verified voltage table or regulator details. Use a current-limited laboratory supply and begin with the manufacturer-prescribed startup sequence. This prevents undocumented rails, adapters, or test fixtures from masking the behavior of the dual 10G Ethernet links.
When transferring a validated XFI/SFI or (R)XAUI design from the evaluation platform to production hardware, preserve the documented reference-plane, connector, and return-path topology as closely as possible. Changes in connector geometry, layer transitions, or cable length can alter insertion loss, jitter, and EDC behavior even when the nominal data rate remains 10 Gb/s. Use the evaluation results to establish channel margins, then validate the final board independently rather than assuming that identical schematic connections produce identical signal integrity.
