Timing Signals Connector

This section describes the GX5055’s Timing connector J8. This 15-pin connector provides external timing, sequencer, and clock connections and is only active for master modules.

The following table lists Timing signals:

Pin	Name	Function	Pin	Name	Function
1	ORun	Output Run Indication	9	GND	Ground
2	OStb	Strobe Output	10	GND	Ground
3	OClk	Clock Output	11	GND	Ground
4	OHalt	Output Halt Indication	12	GND	Ground
5	GND	Ground	13	XPause	External Pause Input (Overrides Pause Command), active low.
6	XClk	External Clock Input	14	XPauseEn	External Pause Input Enable (active low).
7	XTrig	External Trigger Input (Overrides Run Command), active low.	15	XClkEn	External Clock Enable
8	XStb	External Strobe Input
