ML4663
Single Chip 10BASE-FL Transceiver
GENERAL DESCRIPTION
FEATURES
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.
s Single chip solution for 10BASE-FL internal or external
Medium Attachment Units (MAUs)
s Incorporates an AU interface
s Highly stable data quantizer with 55dB input
dynamic range
s Input sensitivity as low as 2mVP-P
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.
s Current driven fiber optic LED driver for accurate
launch power
s Single +5 volt supply
s No crystal or clock required
s Five network status LED outputs
The transmitter automatically inserts 1MHz signal during
Please See ML4668 for New Designsidle 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.
