VSC8664 Quad Port 10/100/1000BASE-T PHY and 100BASE-FX/1000BASE-X SerDes with Recovered Clock Outputs Datasheet

PublishTime：2021-11-16

The VSC8664 device is a low-power, quad Gigabit Ethernet transceiver with dual, fully integrated 1.25 Gbps SerDes interfaces and an I2C multiplexer (mux) to control SFPs or PoE modules. The VSC8664 also includes two recovered clock outputs for Synchronous Ethernet applications. It is designed for use in applications such as multiport switches and routers, where its compact ball grid array (BGA) packaging, low electromagnetic interference (EMI) line driver, and integrated line side termination resistors conserve both power and printed circuit board (PCB) space. Using the VSC8664 device in your design makes it possible to lower the component count without sacrificing capabilities or utility, resulting in more cost-effective production and deployment.
Vitesse’s mixed signal and digital signal processing (DSP) architecture—a key operational feature of the VSC8664 device—assures robust performance even under less-than-favorable environmental conditions. 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. This device also supports 100BASE-FX and 1000BASE-X to connect to fiber modules, such as GBICs and SFPs. In addition, the VSC8664 has an integrated I2C mux to ease the management of fiber optic interface or PoE modules, saving in system cost and valuable PCB space.
The following illustration shows a high-level, generic view of a VSC8664 application.
