AFBR-1150L / AFBR-2150L Fiber Optic Transmitter and Receiver for 150 Mbit/s MOST Data Sheet Description Features MOST150 transmitter and receiver are designed to transmit/ receive up to 150 MBit/s optical data which are DCA coded. Both are packaged in 7-pin transfer molded, lowcost packages ready for assembly into MOST plastic fiber optic connector receptacles. • Optical transmitter and receiver for MOST150 applications with a maximum data rate of 150 Mbit/s The transmitter utilizes a 650 nm LED source with integrated optics for efficient coupling into 1 mm Polymer Optical Fiber (POF), and the receiver contains a high speed PIN diode to receive this light. Input/output data has LVDS 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, transmitter and receiver switch to very low power mode. While in this mode, the devices can sense new data activity and switch back to full operation.
