VSC8664XIC

Overview

The VSC8664XIC is a quad-port Ethernet transceiver manufactured by Microchip Technology. It integrates four 10/100/1000BASE-T PHYs and supports 100BASE-FX and 1000BASE-X SerDes media interfaces with recovered clock outputs. The device operates at data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s. It utilizes I2C, JTAG, MIIM, and SGMII interface types for management and connectivity. Power requirements include minimum and maximum voltages of 1.2 V and 3.3 V. The component functions in full duplex and half duplex modes within an operating temperature range of 0°C to +90°C. It is housed in a BGA-256 package.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package and temperature grade. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement. Ensure supply chain partners provide valid traceability records for quality assurance purposes.

Selection Notes

Select this component when a design requires four independent Gigabit Ethernet ports combined with fiber uplink capabilities via SerDes. Evaluate the BGA-256 footprint constraints during PCB layout planning. Consider the thermal dissipation characteristics associated with the high port density and operating voltage levels specified in the electrical parameters.
