1 / 14 page  March 1997 ML4668 Low Power Single Chip 10BASE-FL Transceiver 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. FEATURES 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 s Up to 100mA maximum 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 BLOCK DIAGRAM 1 AUI RECEIVER Tx SQUELCH AUI DRIVER AUI DRIVER 10MHz GATED OSCILLATOR LOOPBACK MUX JABBER RECEIVE SQUELCH LINK DETECT VREF LED DRIVERS FIBER OPTIC LED DRIVER 1MHz IDLE SIGNAL SQE GND VCC (+5V) +5V LBDIS AGND CTIMER RRSET Tx Rx BIAS GND VCCTx (+5V) +5V RTSET SQEN/JABD Tx+ Tx– COL+ COL– Rx+ Rx– AVCC TxOUT VIN+ VDC VREF VTHADJ VIN– ∫ CMP AMP LMON 14 JAB 28 CLSN 1 RCV 16 XMT 15 18 27 20 12 17 5 10 11 2 3 6 7 19 9 13 8 24 4 23 22 21 25 26 |
