HFBR-150xAFZ / 2555AFZ (SMA Tx/Rx for SERCOS) Full Metal Fiber Optic Transmitter and Receiver for SERCOS Applications Data Sheet Description Features Meets industrial SERCOS standard SERCOS SMA ports SERCOS, an acronym for SErial Realtime COmmunications System, is a standard digital interface for communication 650 nm wavelength technology in industrial CNC applications. SERCOS is a European (EN Metal housing and port 61491) and international standard (IEC 61491). The optical Specified for use with 1 mm plastic optical fiber and interface allows data rates of 2, 4, 8, and 16 MBd and data 200 m hard clad silica transfer between numerical controls and drives via fiber- optic rings, with voltage isolation and noise immunity. Auto-insertable and wave solderable The HFBR-150xAFZ and HFBR-2555AFZ products comply Supports SERCOS 4, 8 and 16 MBd with SERCOS specifications for optical characteristics and RoHS-compliant connector style, and have guaranteed performance at 4, 8, and 16 MBd data rates. Applications Industrial control data links Factory automation data links Voltage isolation applications PLCs Motor drives Sensor, meter and actuator interfaces HCS is a registered trademark of OFS Corporation. 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.Package Information Recommended Chemicals for Cleaning/Degreasing HFBR-150xAFZ and HFBR-2555AFZ Products The HFBR-150xAFZ transmitters and HFBR-2555AFZ re- ceiver are housed in a dual-in-line metal package that is Alcohols: methyl, isopropyl, isobutyl. high strength. The package is designed for auto-insertion Aliphatics: hexane, heptane. and wave soldering so it is ideal for high volume produc- tion applications. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as Handling and Design Information 1,1,1 trichloroethane, ketones such as MEK, acetone, When soldering, it is advisable to leave the protective cap chloroform, ethyl acetate, methylene dichloride, phenol, on the unit to keep the optics clean. Good system per- methylene chloride or N-methylpyrolldone. Also, Avago formance requires clean port optics and cable ferrules to does not recommend the use of cleaners that use halo- avoid obstructing the optical path. Clean compressed air genated hydrocarbons because of their potential environ- often is sufficient to remove particles of dirt. Methanol on mental harm. a cotton swab also works well.

With recommended Tx and Rx circuits (Figure 4 and Figure 5). 2. POF HFBR-ExxyyyZ 0.23 dB/m worst case attentuation. 3. HCS Worst Case Attenuation is 10 dB/km (0 C to 70 C) and 12 dB/km (-40 C to 85 C). 4. Including a 3 dB optical safety margin accounting for link service lifetime. 5. Including a 2 dB optical safety margin accounting for link service lifetime. 6. Signaling rate up to 10 MBd. 7. Signaling rate up to 16 MBd. 8. For PWD calculation, the pulsewidth of the receicer output is compared versus the pulsewidth of the electrical input signal of the transmitter. PWD = PW RXout - PW TXin. Note, that the HFBR-2555AZ is an inverting receiver, thus an electrical high pulse at the transmitter input (LED on) causes an electrical low at the receiver output. For the characterization, the transmitter has been driven with an ideal (duty cycle = 50%) PRBS7 pattern input signal. 2
