HFBR-0AMZ/HFBR-20AMZ Fiber Optic SMA Transmitters and Receivers for MBd SERCOS Applications Data Sheet Description SERCOS, an acronym for SErial Realtime COmmunications Systems, is a standard digital interface for communication in industrial CNC applications. SERCOS is a European (EN 9) and international standard (IEC 9). The optical interface allows data rates of 2,, and MBd and data transfer between numerical controls and drives via fiber-optic rings, with voltage isolation and noise immunity. The HFBR-0AMZ and HFBR-20AMZ products have a guaranteed performance up to MBd. Features RoHS-Compliant Meets Industrial SERCOS MBd standard SMA ports 0 nm wavelength Metal coated, plastic packaging Specified for use with mm POF and 200 µm HCS DC - MBd data rate Applications Industrial Control Data Links Factory Automation Data Links Voltage Isolation Applications
Package Information The RoHS-compliant transmitters and receivers are housed in a low-cost, dual-in-line package that is made of high strength, heat resistant, chemically resistant and UL 9V-O (UL file # E22) flame retardant plastic. Both the transmitter and receiver are coated with a layer of conductive alloy for better air discharge (ESD) performance. The package is designed for auto insertion and wave soldering so it is ideal for high volume production applications. Handling and Design Information When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is sufficient to remove particles of dirt; methanol on a cotton swab also works well. Recommended Chemicals for Cleaning/Degreasing Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as,, trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or N-methylpyrolldone. Also, Avago Technologies does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. CAUTION: The small junction size inherent in the design of these components increases the components susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD. Table.

HFBR-0AMZ Transmitter The HFBR-0AMZ transmitter incoporates a 0nm LED in a metal-coated, plastic housing. The high light output power enables the use of both plastic optical fiber (POF) and Hard Clad Silica (HCS). This transmitter can operate up to MBd using a simple driver circuit. The HFBR-0AMZ is compatible with SMA connectors. BOTTOM VIEW, HFBR-0AMZ SEE NOTE 0 PIN FUNCTION CONNECTED TO PIN CONNECTED TO PIN GND GND CATHODE ANODE Figure.

HFBR-20AMZ Receiver The HFBR-20AMZ receiver is housed in a metal-coated, plastic package, consists of a silicon PIN photodiode and digitizing IC to produce a logic compatible output. The IC includes a unique circuit to correct the pulse width distortion of the first bit after a long idle period. This enables operation from DC to MBd with low PWD for arbitrary data patterns. The receiver is a push-pull stage compatible with TTL and CMOS logic. The HFBR-20AMZ is compatible with SMA connectors. Figure.
