VSC8601 and VSC8641
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.
