Applications

Optical transmitter and receiver for MOST 150 Mbit/s systems (a full description of the MOST  150 system is available at www.mostcooperation.com)

Description

MOST150 transmitter and receiver are designed to trans - mit/ receive up to 150 Mbit/s optical data which are DCA coded. Both are packaged in 7-pin transfer molded, low- cost packages ready for assembly into MOST  plastic fiber optic connector receptacles. The transmitter utilizes a 650 nm LED source with inte - grated 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 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 opera- tion.
