. Digital diagnostics functions are available via a 2-wire serial interface, 

as specified in SFF-8472

5

. The FTLX8573D3BTL is a “limiting module”, i.e., it employs 

a limiting receiver.  Host board designers using an EDC PHY IC should follow the IC 
manufacturer’s recommended settings for interoperating the host-board EDC PHY with a 
limiting receiver SFP+ module. The transceiver is RoHS compliant and lead free per 
Directive 2002/95/EC
