Data Sheet AFBR-58x3xxZ 125-MBd Fast Ethernet Transceiver Description Features ® The Broadcom AFBR-58x3xxZ transceivers provide the Full compatibility with 100BASE-FX version system designer with products to implement a range of IEEE802.3u 125-MBd Fast Ethernet and FDDI as well as 100-Mb/s Full compatibility with FDDI Asynchronous Transfer Mode (ATM) designs. Multisource 1 × 9 package style with choice of duplex SC or duplex ST1 receptacle As an enhancement, the AFBR-5823xxZ transceivers are DMI interface with 2 × 9 devices compatible to SFF-8472 (digital diagnostic interface for Single 3.3V power supply operation optical transceivers). Using the 2-wire serial interface DCPECL differential input and output data connections defined in the SFF-8472 MSA, the AFBR-5823xxZ transceivers provide real-time information on temperature, DCPECL signal detect output bias current, LED average output power, and receiver Industrial temperature range –40°C to 85°C average input power. The interface also adds the ability to Wave solder and aqueous wash process compatible monitor the Receiver Loss of Signal (Rx_LOS). The RoHS compliant transceivers are all supplied in the industry standard 1 × 9 Applications and 2 × 9 package style with either a duplex SC or a duplex ST1 connector interface.

Broadcom AFBR-58x3xxZ-DS100 April 6, 2021 AFBR-58x3xxZ Data Sheet 125-MBd Fast Ethernet Transceiver Transmitter Sections Package The transmitter sections of the AFBR-58x3xxZ series use The overall package concept for the Broadcom transceivers 1300-nm surface-emitting InGaP LEDs. These LEDs are consists of the following basic elements: two optical packaged in the optical subassembly portion of the subassemblies, an electric subassembly, and the housing transmitter section. They are driven by a silicon IC, which as illustrated in Figure 1, Figure 2, Figure 3, and Figure 4. converts differential PECL logic signals, ECL referenced (shifted) to a 3.3V supply, into an analog LED drive current. The package outline drawings and pin out are shown in Figure 5, Figure 6, Figure 7, and Figure 8. The details of this The input of the transmitter sections is internally package outline and pin out are compliant with the AC-coupled. If a DC signal is received, there is no light multisource definition of the 1 × 9 SIP. The low profile of the output. Broadcom transceiver design complies with the maximum height allowed for the duplex SC connector over the entire Receiver Sections length of the package. The optical subassemblies use a high-volume assembly The receiver sections of the AFBR-58x3xxZ series use process together with low-cost lens elements, which result InGaAs PIN photodiodes coupled to a silicon IC, which are in a cost-effective building block. packaged in the optical subassembly portion of the receiver. The electrical subassembly consists of a high-volume, The IC combines the functionality of a transimpedance multilayer printed circuit board on which the IC chips and amplifier and a quantizer providing final pulse shaping for various surface-mounted passive circuit elements are the logical output and the signal detect function. The data attached. output is differential and the signal detect is single ended. Both data and signal detect outputs are PECL compatible, The outer housing including the duplex SC connector ECL referenced (shifted) to a 3.3V power supply. receptacle or the duplex ST ports is molded of filled nonconductive plastic to provide mechanical strength and The receiver has no AC detection implemented. However, if electrical isolation. The solder posts of the Broadcom design the input power gets too low, squelch mode of the receiver are isolated from the circuit design of the transceiver and do is activated and the data output switches to high resistance. not require connection to a ground plane on the circuit board. The transceiver is attached to a printed circuit board with the nine signal pins and the two solder posts that exit the bottom of the housing. The two solder posts provide the primary mechanical strength to withstand the loads imposed on the transceiver by mating with duplex of simplex SC or ST connectored fiber cables.
