VSC8601 (10/100/1000BASE-T PHY with RGMII MAC Interface)
VSC8641 (10/100/1000BASE-T PHY with RGMII and GMII MAC Interface)
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
