+description: |
+  The RT1719 is a sink-only USB Type-C contoller that complies with the latest
+  USB Type-C and PD standards. It does the USB Type-C detection including attach
+  and orientation. It integrates the physical layer of the USB BMC power
+  delivery protocol to allow up to 100W of power. The BMC PD block enables full
+  support for alternative interfaces of the Type-C specification.
