1 / 72 page  © 2006 National Semiconductor Corporation www.national.com DP83848M PHYTER® Mini DP83848J PHYTER® Mini LS Commercial Temperature Single Port 10/100 Ethernet Transceiver October 2006 System Diagram PHYTER® and TRI-STATE® is a registered trademark of National Semiconductor Corporation. Status 10BASE-T or 100BASE-TX MII Typical Ethernet Application Clock LED/s PHYTER Mini PHYTER Mini LS 10/100 Ethernet Transceiver MPU/CPU Source Features • Low-power 3.3V, 0.18 µm CMOS technology • 3.3V MAC Interface • Auto-MDIX for 10/100 Mb/s • Energy Detection Mode • MII Interface • MII serial management interface (MDC and MDIO) • IEEE 802.3u Auto-Negotiation and Parallel Detection • IEEE 802.3u ENDEC, 10BASE-T transceivers and filters • IEEE 802.3u PCS, 100BASE-TX transceivers and filters • Integrated ANSI X3.263 compliant TP-PMD physical su- blayer with adaptive equalization and Baseline Wander compensation • Error-free Operation beyond 137 meters • ESD protection - greater than 4KV Human body model • LED support for Link in DP83848M • LED support for Link and Speed in DP83848J • Supports system clock from oscillator (Not available in DP83848J) • Single register access for complete PHY status • 10/100 Mb/s packet BIST (Built in Self Test) • 40 pin LLP package (6mm) x (6mm) x (0.8mm) General Description The DP83848M/J addresses the quality, reliability and small form factor required for space sensitive applications in embedded systems. The DP83848M/J offers performance far exceeding the IEEE specifications, with superior interoperability and industry leading performance beyond 137m of Cat-V cable. The DP83848M/J also offers Auto-MDIX to remove cabling complications. DP83848M/J has superior ESD pro-tection, greater than 4KV Human Body Model, provid- ing extremely high reliability and robust operation, ensur- ing a high level performance in all applications. DP83848J offers two flexible LED indicators - one for Link and the other for Speed. A 25MHz clock out that eliminates the need and hence the space and cost, of an additional Media Access Control (MAC) clock source component is available only in DP83848M. The DP83848M/J is offered in a tiny 6mm x 6mm LLP 40- pin package and is ideal for industrial controls, build- ing/factory automation, transportation, test equipment and wireless base stations. Applications • Peripheral devices • Mobile devices • Factory and building automation • Basestations |
