The RXM-750 is a fully integrated fiber-optic receiver module suited for SONET OC-1, OC-3, OC-12, and other 45-Mbit/sec to 750-Mbit/sec fiber-optic transmission applications that demand superior performance. The module converts a 45-Mbit/sec to 750-Mbit/sec fiber-optic NRZ signal to differential PECL data outputs. A CMOS flag alerts the user to a loss-of-signal condition when the optical input falls below an acceptable level and a single +5-V supply provides bias for the module's preamplifier and quantizer. The photodiode may be biased with -5 V or grounded. All elements are integrated into a fiber-coupled 1.3-inch x 0.635-inch 20-pin DIL package.
The SU320 series near-infrared camera technology provides sensitivity and high dynamic range coupled with linear response through the 900- to 1,700-nm spectrum.
