AVAGO AFBR-2012S Fiber optic transmitter and receiver for 50 mbaud most Datasheet

AFBR-1012/AFBR-2012
Fiber Optic Transmitter and Receiver
for 50 MBaud MOST®
Data Sheet
Description
Features
AFBR-1012 Transmitter and AFBR-2012 Receiver are designed 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 connector receptacles.
 Operating @ 3.3V or 5V (+/-5% each) Power supply
The transmitter utilizes a 650 nm LED source with integrated 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 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 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 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)
 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 (ICC < 10μA)
 Additional Low Power Mode (ICC < 15μA) for the
transmitter when SP1 input is low
 Signal detect and Status Output
 Pulse width control

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.
