AFBR-1013/AFBR-2013
Fiber Optic Transmitter and Receiver
for 50 MBaud MOST®
Data Sheet
Description
AFBR-1013 Transmitter and AFBR-2013 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 reliability
requirements of automotive applications. It is allowed to
process the AFBR-1013/-2013 devices with reflow solder-
ing. In the absence of data activity, the receiver switches
to very low power mode. While in this mode, the PIN di-
ode 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)
Features
 Solderable with reflow process acc. JEDEC standard
J-STD-020D
 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 (I_CC < 10μA)
 Additional Low Power Mode (I_CC < 15μA) for the
transmitter when SP1 input is low
 Signal detect and Status Output
 Pulse width control
