Description:
The OPF560 series receiver is a low cost soluƟon for high speed fiber opƟc communicaƟon designs.
The output of the receiver is an analog, low impedance, emiƩer follower voltage source capable of driving an amplifier or
level translaƟng circuitry. This allows the subsequent circuitry to use the device in either the analog mode or translated to
ECL/TTL levels for us 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 proporƟonal 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 amplificaƟon of the transimpedance amplifier
makes the output signal much less suscepƟble to EMI.
An AC coupled receiver applicaƟon circuit is shown. Both the 10 W resistor and bypass capacitor are criƟcal.
Applications:
• Industrial Ethernet equipment
• Copper-to-fiber media conversion
• Intra-system fiber opƟc links
• Video surveillance systems
Features:
• Low Cost
• Data Rates up to 155 MBd
• Wide Temperature Range
• SMA, ST, or plasƟc cap style
• Wave Solderable
