Signal levels on (D , D
In ‘suspend’ mode (SUSPND = HIGH) the differential receiver is inactive and output RCV is always
LOW. Out-of-suspend (‘K’) signalling is detected via the single-ended receivers VP and VM.
During suspend, the slew-rate control circuit of low-speed operation is disabled. The (D , D
are still driven to their intended states, without slew-rate control. This is permitted because driving
during suspend is used to signal remote wake-up by driving a ‘K’ signal (one transition from idle to
‘K’ state) for a period of 1 to 15 ms.
VP = VM = H indicates the sharing mode (V
RCV* denotes the signal level on output RCV just before SE0 state occurs. This level is stable during
the SE0 period.
