1. GENERAL DESCRIPTION
The MotorComm YT8511 is a triple-speed 10/100/1000BASE-T Gigabit Ethernet (GbE) Ethernet
physical layer transceiver (PHY). Ideally suited for a wide range of industry applications, it is
manufactured using a standard digital CMOS process and contains all the active circuitry
required to implement the physical layer functions to transmit and receive data on a on
Category 5 unshielded twisted-pair (UTP) cabling.
Based on cutting-edge DSP technology, combing adaptive equalizers, echo canceller, phase-
locked, ADCs, phase-locked loops, line drivers, encoders/decoders, echo cancelers and all other
required support circuitry at a Gigabit data rate to achieve robust performance and exceed
automotive electromagnetic interference (EMI) requirements in severe environments with very
low power dissipation.
The YT8511 is designed to be fully compliant with RGMII interface specifications, allowing
compatibility with standard Ethernet media access controllers (MACs) and switch controllers.
The YT8511 delivers the most comprehensive technology solution required by industry
operating temperature.
