Hello,
I am working a a redesign that uses a Lantronix Wi-PORT NR that takes a UART input and creates a 100BASE-TX copper ethernet connection. These copper ethernet signals are then routed to/from a Microlinear ML6652EM IC that takes wired Ethernet signaling data from a Lantronix WIPORT-NR unit and converts it to fiber based Ethernet through an Avago AFBR-5103AZ. I know that the Avago part was replaced by an AFBR-5803AZ but I cannot find any alternative for the ML6652EM. This circuitry has to be redesigned with currently available parts. Can the DP83849IF IC be wird in such a way to replace the ML6652EM device without using the MAC interface? Or if someone out there has a single and or dual IC solution that would convert either wired Ethernet into a fiber based Ethernet or maybe even something that would take a UART serial data stream (RS-232 TTL Level) or an SPI data interface and be able to convert that into a fiber based Ethernet signaling that would directly interface into a AFBR-5803AZ.
Thanks in advance for your help.
Wes
