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 BLOCK DIAGRAM: VSC8641

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.
