4 / 34 page  4 DS191PP2 CS8904 Crystal LAN™ Quad Ethernet Transceiver CIRRUS LOGIC ADVANCED PRODUCT DATABOOK Each of the CS8904 interface ports support 100, 120, and 150 Ω shielded and unshielded cables, and automatic receive reverse-polarity detection and correction. 1.2 System Applications The CS8904 is designed for use in Ethernet switch, hub, and router systems and in ATM switches with Ethernet support. Offering the latest features of the IEEE 802.3 specification (ISO/IEC 8802-3:1996), the CS8904 can be easily interfaced to custom digital system ASICs. Inputs to the CS8904 from the digital system ASIC are: transmit data, transmit enable, duplex selection, auto-negotiation selection, and loopback selection (loopback from digital system ASIC through CS8904 to digital system ASIC), and mode selection. Mode selection allows the CS8904 to operate with a variety of compatible Ethernet controllers. Outputs of the CS8904 to the digital system ASIC are: transmit clock, receive clock, receive data, and five status lines: collision detect, carrier detect, jabber indication, duplex (half / full), and auto- negotiation (active / inactive). The Link Status LED indicates that there is an operational link with the remote network device. 1.3 Key Features and Benefits 1.3.1 Low Cost, Low Noise, More Features • High-performance on-chip 10BASE-T filters allow designers to use simple isolation trans- formers instead of more costly filter/transform- er packages. • The CS8904 is designed to be used on a 4-layer circuit board instead of a more expensive multi- layer board, saving board manufacturing costs. • The CS8904 has been designed for very low noise emission. As a result FCC testing and qualification time is reduced considerably. • Half and full duplex operation make the CS8904 ideal for use in 10BASE-T Ethernet switch designs and in ATM switch systems that require 10BASE-T Ethernet ports. • Auto-Negotiation capability that is fully com- pliant with the latest IEEE Ethernet specifica- tion (ISO/IEC 8802-3:1995(u)) provides the newest Ethernet features to system designers. |
