ML4668 General Description
The ML4668 single-chip 10BASE-FL transceiver is a low power, high output current, plug-compatible version of the industry standard ML4663. The ML4668 offers a standard IEEE 802.3 AU interface that allows it to be directly connected to industry standard manchester encoder/ decoder chips or an AUI connector.
The ML4668 provides a highly integrated solution that requires a minimal number of external components, and is compliant to the IEEE 802.3 10BASE-FL standard. The transmitter offers a 100mA maximum current drive output that directly drives a fiber optic LED transmitter. The receiver offers a highly stable fiber optic data quantizer capable of accepting input signals as low as 2mVP-P with a 55dB dynamic range.
The transmitter automatically inserts 1MHz signal during idle time and removes this signal on reception. Low Light is continuously monitored for both activity as well as power level. Five LED status indicators monitor error conditions as well as transmissions, receptions and collisions.
ML4668 Maximum Ratings
Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.
