VSC8601 (10/100/1000BASE-T PHY with RGMII MAC Interface)

VSC8641 (10/100/1000BASE-T PHY with RGMII and GMII MAC Interface)

Application Diagram

Lowest Power

• Industry’s lowest power consumption 10/100/1000BASE-T PHY at 600 mW

• Powered by a single 3.3 V supply by using the optional on-chip switching regulator; eliminates the need for 1.2 V supply

• Advanced power management complies with Wake-on-LAN™ and PCI2.2 power requirements

Wide Range of Support

• Supports RGMII versions 1.3 and 2.0 (2.5 V, 3.3 V) MAC interface

• Supports GMII/MII (2.5 V, 3.3 V) MAC interface (VSC8641)

• Compliant with IEEE 802.3 (10BASE-T, 100BASE-TX, 1000BASE-T) specifications

• IEEE 1149.1 JTAG boundary scan support for improved reliability

• Greater than 10 kB jumbo frame support in all speeds to support custom SAN and LAN systems

• Legacy Power-over-Ethernet support, including intelligence for detection and activation

Flexibility

• Low EMI line driver with integrated line side termination resistors for a better performing design

• VeriPHY® cable diagnostics suite provides extensive network cable information such as cable length, termination status,

and open/short fault location

• ActiPHY™ power management system with built-in intelligence and saving modes

• Suite of test modes, including loopback paths, Ethernet packet generators, and CRC counters to simplify design

• Programmable direct drive LEDs (three in VSC8601 and four in VSC8641), which eliminate external components and

reduce EMI

Applications

• LAN-on-Motherboards, mobile PCs, and single-port RGMII applications

• Broadband CPE and wireless routers

• Gigabit Ethernet SAN, NAS, and MAN systems

• iSCSI and TOE applications

• Network-enabled devices such as printers, IP phones, and gaming appliances

• ATCA™ 3.0 and PICMG™ 2.16 Ethernet backplane applications

• GE-PON physical media dependent device (VSC8641)
