January 1997 ML6680 Token Ring Copper-to-Fiber Converter GENERAL DESCRIPTION The ML6680 is a single-chip conversion between Token Ring ISO/IEC8802-5 copper-based media and Token Ring ISO/IEC8802-5 fiber-based media. The ML6680 fiber-optic interface contains a data quantizer, circuitry for fiber optic key signal generation and recognition, pin-selectable signal switching, and current driven transmitter outputs. The ML6680 copper interface consists of a twisted pair line equalizer, receive squelch circuit, pin selectable phantom wire fault detection and signal switching, and a transmit driver. This section supports the ISO/IEC8802-5 standard requirements. The ML6680 provides an optional PECL compatible interface. The ML6680 may be configured to one of four modes: 1. 2. 3. 4.
