AFBR-59SMI2Z Datasheet | Broadcom

Description The Avago Technologies AFBR-59SMI2Z transceiver provides system designers with the ability to support serial munication with baud rates of up to 250 MBd over 2.2-mm jacketed standard polymer optical fiber (POF) with 1-mm core diameter and NA 0.5. The SMI optical interconnect with its push-pull positive latching, with safe-release mechanism, provides secure, safe and easy to mate and de-mate optical connection for miscellaneous industrial and medical applications. The AFBR-59SMI2Z is Laser Class 1, lead-free and pliant with Ro HS. Transmitter The transmitter consists of a 650-nm LED, which is controlled by a fully integrated driver IC. The LED driver operates at 3.3V. It receives Low Voltage Differential Signaling (LVDS) electrical input, and converts it into a modulated current driving the LED. LED and driver IC are packaged in an optical subassembly. The optimized lens system of the optical subassembly couples the emitted optical power very efficiently into 1-mm core POF cable. Receiver The receiver utilizes a fully integrated single chip solution, which provides excellent immunity to EMI and fast transient d V/dt rejection. The receiver directly converts light to a digital LVDS output signal and operates at 3.3-V nominal supply. The integrated receiver is packaged in an optical subassembly, which couples optical power efficiently from POF to the receiving PIN. The receiver features an analog monitor output of the ining optical signal. The monitor output provides an analog voltage proportional to the average optical input power. In absence of receiver optical input signal, the receiver is in low power sleep mode and the differential output signal is pulled to ground. The receiver wakes up, when a valid optical input signal is detected.
