Overview
The BCM84758AKFSBG is a quad-port 10 Gigabit Ethernet PHY transceiver from Broadcom Limited. It integrates four independent SFI and XFI serial interfaces to support high-speed data transmission over fiber optic or copper media. The device complies with IEEE 802.3ae standards for 10GBASE-SR, -LR, -ER, and -ZR applications. Designed for telecom and enterprise networking equipment, it provides low-latency packet forwarding capabilities essential for core and aggregation layer switches.
Feature Summary
- Integrates four independent 10GbE physical layer channels
- Supports both SFI and XFI serial interface standards
- Compliant with IEEE 802.3ae specifications for long-reach optical links
Applications
- Telecom carrier-grade routing platforms
- Enterprise core and distribution layer switches
- High-density server interconnect systems
Procurement Notes
Verify the specific suffix 'AKFSBG' against the official Broadcom datasheet to confirm package type and temperature range. Ensure compatibility with existing PCB layout constraints for the QFN package. Confirm RoHS compliance status through the manufacturer's latest product change notifications before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring multiple 10Gbps optical uplinks with minimal latency. It is suitable for applications demanding IEEE 802.3ae compliance without external PHY controllers. Evaluate power consumption requirements against system thermal limits, as quad-port implementations generate significant heat during continuous operation.
Part Context
This part belongs to Broadcom’s portfolio of high-performance Ethernet PHY solutions. It complements broader switching ASIC families by providing the physical layer connectivity necessary for multi-gigabit backbone infrastructure. The device supports advanced diagnostics and monitoring features typical of modern telecom-grade networking hardware.
Replacement Considerations
Consult Broadcom documentation for direct pin-compatible alternatives within the same family. Verify that any substitute maintains identical SFI/XFI signaling characteristics and regulatory compliance certifications.
