Product Bulletin OPF560 February 1996 125 MHz Fiber Optic Receiver Types OPF560, OPF561, OPF562 OPF560 VCC VEE OUTPUT OPF561 OUTPUT VEE Features Low Cost Data Rates up to 155 MBd Wide Temperature Range SMA, ST*, or plastic cap style www.DataSheet4U.com Wave Solderable Description The OPF560 series receiver is a low cost solution for high speed fiber optic communication designs. The output of the receiver is an analog, low impedance, emitter follower voltage source capable of driving an amplifier or level translating circuitry. This allows the subsequent circuitry to use the device in either the analog mode or translated to ECL/TTL levels for use in a digital mode at data rates up to 155MBaud. The receiver is comprised of a high speed, low noise, photodiode coupled to a transimpedance amplifier which produces an output voltage proportional to the input light amplitude. This hybrid approach solves many of the problems of high speed data link designs by placing a pre-amplifier close to the photodiode. The amplification of the transimpedance amplifier makes the output signal much less susceptible to EMI. An AC coupled receiver application circuit is shown. Both the 10 ohm resistor and by-pass capacitor are critical. *ST is a registered trademark of AT&T.
