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
encountered in copper-wired environments.
