Broadcom AFBR-58x3xxZ 125MBd Fast Ethernet Transceivers

Broadcom AFBR-58x3xxZ 125MBd Fast Ethernet Transceivers provide the system designer with products to implement a range of 125MBd Fast Ethernet and FDDI, as well as 100Mb/s Asynchronous Transfer Mode (ATM) designs. As an enhancement, the AFBR-5823xxZ transceivers are compatible with SFF-8472 (digital diagnostic interface for optical transceivers). Using the 2-wire serial interface defined in the SFF-8472 MSA, the Broadcom AFBR-5823xxZ transceivers provide real-time information on temperature, bias current, LED average output power, and receiver average input power. The interface also adds the ability to monitor the Receiver Loss of Signal (Rx_LOS). The transceivers are all supplied in the industry-standard 1×9 and 2×9 package style with either a duplex SC or a duplex ST1 connector interface.
