Applications
Optical transmitter and receiver for MOST150 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
ber optic connector receptacles.
The transmitter utilizes a 650 nm LED source with inte-
grated optics for ecient 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 specied 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.
