VSC8488YJU

Overview

The VSC8488YJU is a dual-channel 10 Gigabit Ethernet transceiver manufactured by Microchip Technology. It supports data rates of 10 Gb/s and operates with supply voltages of 1.2 V and 1.8 V. The device utilizes an FCCSP-196 package for surface mount installation. Interface capabilities include 2-Wire, MDIO, and SPI protocols for control and configuration. The component is designed for high-performance networking applications requiring reliable 10GbE connectivity.

Feature Summary

• Dual-channel architecture supporting simultaneous 10 GbE transmission and reception
• Integrated clock recovery and data retiming for signal integrity
• Support for standard MDIO and SPI management interfaces
• Optimized for low power consumption in dense packaging

Applications

• High-speed network switches and routers
• Telecommunications infrastructure equipment
• Data center interconnects
• Enterprise networking hardware

Procurement Notes

Verify the current lifecycle status before procurement as the component may be subject to discontinuation notices. Confirm that the FCCSP-196 package compatibility matches your PCB design requirements. Ensure that the required supply voltage levels of 1.2 V and 1.8 V are available on your target board. Check for any specific environmental compliance documentation if operating in regulated regions.

Selection Notes

Select this component when a dual-channel solution is sufficient for the design. Consider the VSC8489YJU-10 if XAUI interface support is required instead of SFI/XFI. Evaluate the VSC8484YJP if four independent channels are needed despite the larger BGA footprint. Verify that the system architecture can accommodate the specific voltage domains required for operation.

Part Context

The VSC8488YJU belongs to the VSC848x family of 10 Gigabit Ethernet PHYs from Microchip. This series provides integrated solutions for 10GbE applications, balancing performance with power efficiency. The YJU suffix indicates the specific package type and temperature range classification within the product line.
