AFBR-1012/AFBR-2012 Fiber Optic Transmitter and Receiver for 50 MBaud MOST® Data Sheet Description Features AFBR-1012 Transmitter and AFBR-2012 Receiver are designed 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 connector receptacles. Operating @ 3.3V or 5V (+/-5% each) Power supply The transmitter utilizes a 650 nm LED source with integrated optics for efficient coupling into 1mm Polymer Optical 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 operation. 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) 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.

The current through the LED and therefore the optical output power and overall power consumption depends on the settings of REXT. The nominal value for REXT is 15k. With REXT = 30k the optical output power is about -3dB of the nominal value. Important: The external resistor of REXT must be within the range of 13.5kΩ to 33kΩ. For values out of this range functionality may not be given over the whole temperature range and the device lifetime. 2. If the transmitter is in full power mode it is switched OFF 1ms (max) after Tx DATA is low. If the transmitter is in low power mode it is switched ON 6ms (max) after Tx Data transmission starts.
