Attach the Samtec BullsEye connector to the GTH Quad 115
indexing pins on the bottom of the connector with the guide holes on the board. Hold the
connector flush with the board and fasten it by tightening the two captive screws.

inputs. Connect these cables to the SuperClock-2 module as follows:
• CLK0_P coax cable → SMA connector J5 (CLKOUT1_P) on the SuperClock-2 module
• CLK0_N coax cable → SMA connector J6 (CLKOUT1_N) on the SuperClock-2 module
Any one of the five differential outputs from the SuperClock-2 module can be used to source
Note:
the GTH reference clock. CLKOUT1_P and CLKOUT1_N are used here as an example.
