Product Description

DP83TC812SRHARQ1 connects a host MAC to a 100 Mbps single-pair automotive Ethernet link. The S option includes SGMII among its MAC-side choices, but that interface does not change the 100BASE-T1 cable-port speed.

TC-10 sleep retains wake functionality using the separate sleep rail while other supplies are off. Diagnostic functions such as cable reflectometry and signal-quality indication support link bring-up and fault investigation.
