ML4662 General Description
The ML4662 10Base-FL transceiver combined with the ML4622 or ML4624 fiber optic quantizers provides all of the functionality required to implement both an internal and external IEEE 802.3 10Base-FL MAU. The ML4662 offers a standard IEEE 802.3 AU interface that allows it to be directly connected to industry standard manchester encoder/decoder chips or and AUI cable.
The ML4662 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 current driven output that directly drives a fiber optic LED transmitter. Jabber, a 1MHz idle signal, and SQE Test are fully integrated onto the chip.
The receiver accepts and ECL level input coming from the ML4622 or ML4624 fiber optic quantizers. The 1MHz idle signal is removed and the AUI output is activated when the receive squelch criteria is exceeded. A Link Monitor function is also provided for low light detection.
ML4662 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.

ML4663 General Description
The ML4663 single-chip 10BASE-FL transceiver integrates both a ML4662 10BASE-FL transceiver with a ML4622 fiber optic data quantizer to implement a highly integrated solution for 10BASE-FL transceivers. The ML4663 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 ML4663 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 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.
ML4663 Maximum Ratings
Absolute maximum ratings are limits beyond which the life of the integrated circuit may be impaired. All voltages unless otherwise specified are measured with respect to ground.
