SCDT
14
DO
Sync detect – Output to signal when the link is active or inactive. The link is considered to be active when DE is
actively switching. The TFP9431 monitors the state DE to determine link activity. SCDT can be tied externally
to PDO to power down the out put drivers when the link is inactive.
High: Active link
Low: Inactive link
ST

DI
Output drive strength select – Selects output drive strength for high or low current drive for digital outputs. (See
dc specifications for IOH and IOL vs ST state.)
High : High drive strength
Low : Low drive strength
