AFBR-1012/AFBR-2012

Fiber Optic Transmitter and Receiver

for 50 MBaud MOST®

Data Sheet

Features

 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® Speci cation of Physical

Layer Rev 1.1”

 RoHS compliant (Lead free and halogen free)

 Lead is  ash gold

 Low power consumption

 Photo current sensing, network activity detection and

Low Power Mode (ICC < 10μA)

 Additional Low Power Mode (ICC < 15μA) for the

transmitter when SP1 input is low

 Signal detect and Status Output

 Pulse width control

Description

AFBR-1012 Transmitter and AFBR-2012 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  ber optic connec-

tor receptacles.

The transmitter utilizes a 650 nm LED source with inte-

grated optics for e cient 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 speci ed 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 op-

eration.

Notes:

1. 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.
