General Description
ML6680 General Description
The ML6680 is a single-chip conversion between TokenRing ISO/IEC8802-5 copper-based media and Token Ring ISO/IEC8802-5 fiber-based media. The ML6680 fiber-opticinterface contains a data quantizer, circuitry for fiber optickey signal generation and recognition, pin-selectablesignal switching, and current driven transmitter outputs.
The ML6680 copper interface consists of a twisted pairline equalizer, receive squelch circuit, pin selectablephantom wire fault detection and signal switching, and atransmit driver. This section supports the ISO/IEC8802-5standard requirements. The ML6680 provides an optionalPECL compatible interface.
The ML6680 may be configured to one of four modes:
1. Standard Media Converter
2. Concentrator Media Converter
3. Lobe or Ring Out Port Media Converter
4. Ring In Port Media Converter
