PRODUCT BRIEF
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

General Description
Designed for high-performance, low-power, and low-cost
Gigabit Ethernet, the VSC8601 and VSC8641 are the
industry’s lowest-power and most highly integrated Gigabit
Ethernet (GbE) PHYs. The VSC8601 is optimized for
Gigabit LAN on Motherboard (GLOM) and Gigabit Ethernet
switch applications, while the VSC8641 is optimized for
Gigabit Ethernet Passive Optical Network (GE-PON)
applications.
The devices feature integrated, line side termination to
simplify PCB design, maximize board space, and create a
cleaner, higher-performance product. To further reduce
complexity, component count, and system cost, they
include an internal 1.2 V power regulator that operates on a
single 3.3 V supply. Additionally, integrated RGMII timing
compensation eliminates the need for on-board delay lines.
Vitesse’s mixed signal and digital signal processing (DSP)
architecture assures robust performance. It supports both
half-duplex and full-duplex 10BASE-T, 100BASE-TX, and
1000BASE-T communication speeds over Category 5
(Cat5) unshielded twisted pair (UTP) cable at distances
greater than 140 m, displaying excellent tolerance to NEXT,
FEXT, echo, and other types of ambient environment and
system electronic noise.
