1 / 9 page  AFBR-1012/AFBR-2012 Fiber Optic Transmitter and Receiver for 50 MBaud MOST® Data Sheet Features Operating @ 3.3V or 5V (+/-5% each) Power supply Operating temperature range -40°C to +95°C TTL Data Input/ Output (Logic to Light Function) Power down mode During the low power mode a receiver STATUS-pin indicates if modulated light is received (Light on -> STATUS = low). The power supply of the whole MOST device can be switched on with this Status-pin. Duty Cycle Adjust (DCA), yields to enhanced SP1 input range 650nm for working in a low attenuation range of PMMA Fiber -25dBm guaranteed sensitivity @ 650nm Fully compliant to “MOST® Specification of Physical Layer Rev 1.1” RoHS compliant (Lead free and halogen free) Lead is flash gold Low power consumption Photo current sensing, network activity detection and Low Power Mode (ICC < 10μA) Additional Low Power Mode (ICC < 15μA) for the transmitter when SP1 input is low Signal detect and Status Output Pulse width control Description AFBR-1012 Transmitter and AFBR-2012 Receiver are de- signed to transmit/ receive up to 25MBit/s optical data which are biphase coded (up to 50Mbaud). Both are packaged in 4-pin transfer molded, low-cost packages ready for assembly into MOST® plastic fiber optic connec- tor receptacles. The transmitter utilizes a 650 nm LED source with inte- grated optics for efficient coupling into 1mm Polymer Op- tical Fiber (POF), and the receiver contains a high speed PIN diode to receive this light. Input/output data has TTL switching levels, compatible with MOST® Network Interface Controller ICs. These optical components are specified for operation over a -40°C to +95°C temperature range, and meet the reliability requirements of automotive applications. In the absence of data activity, the receiver switches to very low power mode. While in this mode, the PIN diode can sense new data activity and switch the receiver back to full op- eration. Applications Optical Transmitter and Receiver for MOST® 50 Mbaud systems (a full description of the MOST® 50 Mbaud system is available at www.mostcooperation.com) |
