MT90710

® CMOS MT90710 High-Speed Isochronous Multiplexer Preliminary Information Features Multiplexes eight 2.048 Mbit/s, ST-BUS links onto one serial high-speed 20.48 Mbit/s link 15.808 Mbit/s clear bandwidth transport Two 8 kbit/s and one 32 kbit/s oversampled signalling channels Embedded system timing and frame synchronization Frame buffer control signals generated on-chip Check-sum generated on multiplexed frame Remote synchronization indication Both master and slave timing mode operation On-chip reference generation for slave mode synchronization 4B/5B data encoding/decoding MT90710AP ISSUE 1 January 1995 Ordering Information 84 Pin PLCC 0 °C to +70 °C Description The High-Speed Isochronous Multiplexer integrated circuit multiplexes up to eight Serial Telecom (ST-BUS) links onto a single 20 MHz loop to facilitate point-to-point data transport requirements. The MT90710 connects easily with standard Fiber Optic interfaces to form a complete electric to photonic conversion circuit. Optical transmission allows large bandwidth inter-shelf or, in distributed systems, inter-node communication by eliminating multiple data buses, cable inter-connect and attendant driver interfaces. The final result is a simple physical interface free of the radiated emissions and background noise susceptibility problems encountered in copper-wired environments.
