HFBR-5764AP Multimode Small Form Factor Pluggable Transceivers for 200 MBd SBCON Data Sheet The HFBR-5764AP transceiver from Avago Technologies is compatible with the SBCON specificationandtheIBMESCONarchitecture. This transceiver conforms to the industry standard Small Form Pluggable SFP form factor. This transceiver operates at a nominal wavelength of 1300 nm with an LC fiber connector interface with an external connector shield. Transmitter Section • SBCON 200 MBd specification • Industry standard Small Form Pluggable SFP package • LC duplex connector optical interface • Single V power supply • V TTL LOS output • Manufactured in an ISO 9001 certified facility • Temperaturerange: -20 °C to +85 °C • Bail de-latch option HFBR-5764AP The transmitter section utilizes a 1300 nm InGaAsP LED. This LED is packaged in the optical subassembly portion of the transmitter section. It is driven by a custom silicon IC which converts differential PECL logic signals, ECL referenced shifted to a V supply, into an analog LED drive current. Receiver Section • Interconnection with IBM compatible processors, directors and channel attachment units Disk and tape drives Communication controllers • Data communication equipment Local area networks Point-to-point communication The receiver section utilizes an InGaAs PIN photodiode coupled to a custom silicon transimpedance preamplifier IC. It is packaged in the optical subassembly portion of the receiver. This PIN/preamplifier combination is coupled to a custom quantizer IC which provides the final pulse shaping for the logic output and the Loss of Signal LOS function. The data output is differential. The data output is PECL compatible, ECL referenced shifted to a V power supply. This circuit also includes a loss of signal LOS detection circuit which provides an open collector logic high output in the absence of a usable input .optical signal. The LOS output is V TTL. Transmitter Disable The HFBR-5764AP accepts a transmit disable control signal input which shuts down the transmitter. A high signal implements this function while a low signal allows normal LED operation. Loss of Signal The Loss of Signal LOS output indicates that the optical input signal to the receiver does not meet the minimum detectable level for SBCON compliant signals. When LOS is high it indicates loss of signal. When LOS is low it indicates normal operation. The LOS thresholds are set to indicate a definite optical fault has occurred e.g., disconnected or broken fiber connection to receiver, failed transmitter . Module Package The transceiver meets the Small Form Pluggable SFP industry standard package utilizing an integral LC duplex optical interface connector. The hot-pluggable capability of the SFP package allows the module to be installed at any time even with the host system operating and on-line. This allows for system configuration changes or maintenance without system down time. The HFBR-5764AP uses a reliable 1300 nm LED source and requires a V dc power supply for optimal design. Module Diagrams Figure 1 illustrates the major functional components of the HFBR-5764AP. The connection diagram of the module is shown in Figure Figures 5 and 7 depict the external configuration and dimensions of the module.
