ML6651

ADVANCED Information ML6651 Auto-Negotiating Media Converter GENERAL DESCRIPTION The ML6651 converts signals transmitted between twisted pair and fiber optic Ethernet technologies. It supports conversion between 10BASE-T and 10BASE-FL, between 100BASE-TX and 100BASE-FX/SX, and between FLP (fast link pulse) bursts and FLNP (fiber link negotiation pulse) bursts. Either 850nm or 1300nm laser optics can be used for both 10 and 100 Mb/second operating data rates while fully auto-negotiating for speed and duplex mode communication. One or both of the fiber optic and twisted pair interfaces can be set to interface with industry standard 1x9 fiber optic PMD modules, using PECL or LVPECL compatible modes. FEATURES s Complete implementation of fiber optic and twisted pair media interface s ISO/IEC 8802.3, IEEE 802.3 and TIA/EIA-785 compliance, including full auto-negotiation for twisted pair and fiber optic media s 850nm, 1300nm and 1x9 PMD modules s Supports 1:1 receiver/transmitter transformer ratio for twisted pair s Low latency 10Mb/s path s Integrated voltage and current references s Integrated twisted pair output wave shaping eliminate external filtering s Integrated twisted pair 10BASE-T input filter and 100BASE-TX equalizer with baseline wander correction circuit ADVANCED DATASHEET September 2000 ADVANCED TABLE OF CONTENTS ML6651 General Description ..............................................................................................................................
