6 Event Pulse asynchronous bridge

The css600_eventpulseasyncbridge Event Pulse asynchronous bridge is used where an event signal, or a group of events, must cross a clock or power domain boundary.

The bridge has the following features:

  • Two independent clock domains with any phase or frequency alignment.
  • Two independent power domains, either of which can be switched relative to the other.
  • Three Q-Channel LPIs for slave side clock, master side clock, and power switching management.
  • Two-part meta-component with separate slave and master side components.
  • Configurable up to 32-bits wide for transporting multiple events across the same boundary.

The following figure shows the external connections on the Event Pulse asynchronous bridge.
