AFBR-1010/AFBR-2010 Fiber Optic Transmitter and Receiver for 50 MBaud MOST(R) Data Sheet Transmitter (EOC) Description AFBR-1010 Transmitter and AFBR-2010 Receiver are packaged in 4-pin transfer molded, low-cost packages ready for assembly into plastic fiber optic connector receptacles compliant with MOST (R) technology. The transmitter utilizes a 650 nm LED source with integrated optics for efficient coupling into 1 mm Polymer Optical Fiber (POF), and the receiver contains a large area PIN diode to receive this light. Input/output data has TTL switching levels, compatible with MOST(R) Network Interface Controller ICs. These optical components are specified for operation over a wide -40 C to +95 C extended temperature range, and meet the rigorous 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. Receiver (OEC) Features * Optical transmitter (EOC) and receiver (OEC) for use in MOST(R) equipment for up to 50 Mbaud * Compliant to MOST(R) Specification of Physical Layer Rev 1.1 * Operating temperature range of -40C to +95C * Reliability performance per automotive application requirements * Lead is flash gold Applications * Optical Transmitter and Receiver for MOST(R) 50 Mbaud systems (A full description of MOST(R) 50 Mbaud information and entertainment LAN system and standards are available at www.mostcooperation.com) MOST(R) is a registered trademark of MOST Corperation.

Absolute Maximum Ratings are those values beyond which damage to the device may occur if these limits are exceeded for other than a short period of time. See Reliability Data Sheets for specific reliability performance. 2. Measured 1 cm outside of MOST(R) optical connector housing (header) on a MOST(R) application PCB. The optical components (EOC and OEC) are inside the header connector assembly composed of the plastic housing and EMI shield, that is, airflow is restricted to natural convection. 3. The CONT input is a digital function. An open circuit will select lower (normal light output -3 dB), and a short circuit to VCCT will select normal light output power. This makes the LED meet eye safety under this fault condition. 4. A safety resistor of 50 W (minimum) is to be connected between Data Out and the receiving circuitry. The receiving circuitry must be powered up within 50 ms after Mode Out goes low to prevent permanent damage to the OEC. 2 Recommended Operating Conditions Parameter Symbol Min. Typical Max.
