Description
USB high speed IO buffer (D−).
USB high speed IO buffer (D+).
USB full speed output buffer (D+). RSDP also
functions as a current sink for termination during
HS operation.
RPU sources power for the 1.5K ohm resistor
attached to D+ during full speed operation.
PLL voltage reference. Current source for 9.1K
ohm resistor (1%) connected to AVSS.
Fabrication only. Connect to VSS.
