odin mor4 02 fiber optic receiver for most? data sheet description the 4-pin most optical receiver (odin mor4 02) is a highly integrated cmos ic combined with a high speed pin diode designed to receive up to 25 mbit/s optical data which is biphase coded (up to 50 mbaud) and convert this optical data to a rail-to-rail data stream. during the low power mode, the pin diode is still being observed and if activity is detected, the receiver will switch to full power mode. a status-pin indicates if modulated light is received (light on -> status = low). with the status-pin the power supply of the whole most device can be switched on. the power supply voltage is either 3.3v or 5v. applications ? optical receiver for most systems features excellent solution for converting high speed data from plastic optical fiber (pof) to digital output. ? operating @ 3.3v or 5v power supply ? high speed receiver up to 25 mbit/s net data rate (50 mbaud) ? 95c operating temperature over whole life time ? photo current sensing, network activity detection and low power mode (i cc < 10 a) ? signal detect and status output ? low power consumption ? pulse width control ? -25dbm guaranteed sensitivity @ 650nm for working in a low attenuation range of pmma fiber ? fully compliant to most? specifcation of physical layer rev 1.1 ? rohs compliant (lead free and halogen free)
