AFBR-1555ARZ, AFBR-2555ARZ (SMA Tx/Rx for SERCOS) Reinforced Metal Fiber Optic Transmitter and Receiver for SERCOS Applications Data Sheet Description Features Meets industrial SERCOS standard SERCOS SMA ports 650-nm wavelength technology The Serial Realtime Communications System (SERCOS) is a standard digital interface for communication in industrial CNC Reinforced metal housing and port applications. SERCOS is a European (EN 61491) and Specified for use with 1-mm plastic optical fiber and international standard (IEC 61491). The optical interface allows 200-m plastic clad silica PCS data rates of 2, 4, 8, and 16 MBd and data transfer between Auto-insertable and wave solderable numerical controls and drives via fiber optic rings, with voltage Supports SERCOS 2, 4, 8 and 16 MBd isolation and noise immunity. The AFBR-1555ARZ and RoHS-compliant AFBR-2555ARZ products comply with SERCOS specifications for optical characteristics and connector style, and have guaranteed performance at 2, 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 Broadcom - 1 -AFBR-1555ARZ, AFBR-2555ARZ Package and Handling Information (SMA Tx/Rx for SERCOS) Data Sheet Recommended Chemicals for Cleaning/ Package and Handling Information Degreasing AFBR-1555ARZ and AFBR-2555ARZ Products Package Information Alcohols: methyl, isopropyl, isobutyl. The AFBR-1555ARZ transmitter and AFBR-2555ARZ receiver are housed in a dual-in-line metal package, which is reinforced by a Aliphatics: hexane, heptane. metal brace. This provides very high mechanical robustness. Other: soap solution, naphtha. The package is designed for auto-insertion and wave soldering. Therefore, it is ideal for high volume production applications. Do not use partially halogenated hydrocarbons such as 1,1,1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene Handling and Design Information chloride or N-methylpyrolldone. Also, Avago does not When soldering, it is advisable to leave the protective cap on recommend the use of cleaners that use halogenated the unit to keep the optics clean. Good system performance hydrocarbons because of their potential environmental harm. 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. Specified Link Performance 40C to +85C, unless otherwise noted.

For PWD calculation, the pulse width of the receiver output is compared versus the pulse width of the electrical input signal of the transmitter. PWD = PW RXout PW TXin. Note that the AFBR-2555ARZ 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. Broadcom - 2 -
