Timing Module Connectors

This topic describes GX5105 Timing Module connector J1. This 68-pin, very high-density (VHD) connector handles UUT timing and external event signals.

Timing Module 68-Pin (VHD) Connector

The following table lists GX5105 Timing signals:

Pin	Name	Function	Pin	Name	Function
1	EXT0	External event 0	18	ORUN	Run Indication
2	EXT1	External event 1	19	GND
3	EXT2	External event 2	20	BCLK	Independent user defined programmable clock output
4	EXT3	External event 3	21	GND
5	EXT4	External event 4	22	OCLK	Clock Output
6	EXT5	External event 5	23	GND
7	EXT6	External event 6	24	OSTB	Strobe Output
8	EXT7	External event 7	25	GND
9	EXT8	External event 8	26	XTRIG	External Override Run Cmd.
10	EXT9	External event 9	27	XPAUSE	External Override Pause Cmd.
11	EXT10	External event 10	28	XCEN	External Clock Enable
12	EXT11	External event 11	29	XSTBEN	External Strobe Enable
13	EXT12	External event 12	30	GND
14	EXT13	External event 13	31	XCLK	External Clock Input
15	EXT14	External event 14	32	XSTB(1)
16	EXT15	External event 15	33	NC(1)	External Strobe Input
17	GND		34	NC(2)
35	GND		67	NC / VCC(3)	VCC via jumper
66	GND		68	NC(2)

68-pin Connector J1 (timing) to UUT Unspecified pins are GND
