SPFBFT302

• Optical transmitter and receiver for maximum datarate 10 Mbaud (half duplex burst mode)
• Transmitter: LED with 650 nm for working in low attenuation range of PMMA fiber
• Receiver: Photodiode with preamp, digitizer with DC elimination circuit (tracked decision threshold), Sleep - and Wake-up-Function, output stage (electrical output driver)
• Built in transmitter and receiver gate for half duplex mode (mutual blocking of transmitter and receiver)
• Operation at 5V or 8V-11V power supply voltage
• Built in pulse width detection for indicating Sync, Alarm and continuous light on (integrated time basis to differentiate and evaluate Sync, Alarm and Continuous Light conditions Alarm output)
• Diagnose function for photocurrent
• Mechanical assembly: 6 Pin CAI package for easy coupling of POF (plastic optical fiber) with insert

The SPFBFT302 comprises of the functional groups as shown in the block wiring diagram which are defined in more detail below. The following applies in standard mode: Low level to Dl means LED driver is active and therefore the LED is emitting light. If light falls onto the photodiode, the DO driver becomes active and produces low level on DO.
