6 Event Pulse synchronous bridge

The css600_eventpulsesyncbridge Event Pulse synchronous bridge is used where an event signal, or a group of events, must cross a power domain boundary.

The bridge has the following features:

  • Two synchronous clock domains with any frequency difference. The clocks must be skew balanced and from a common source so that they are high-level-gated by a common control point.
  • Two independent power domains, either of which can be switched relative to the other.
  • Two Q-Channel LPIs for 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 synchronous bridge.
