ML628 IBERT Getting Started Guide

UG806 (v1.0) May 20, 2011

Running the GTH IBERT Demonstration

GTH Transceiver Clock Connections

Refer to

Figure 1-2, page 8

to identify the P and N coax cables that are connected to the

reference clock (CLK0). 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)

Note:

Any one of the five differential outputs from the SuperClock-2 Module can be used to source

the GTH reference clock. CLKOUT1_P and CLKOUT1_N are used here as an example.

GTH TX/RX Loopback Connections

Refer to

Figure 1-2, page 8

to identify the P and N coax cables that are connected to the four

receivers (RX0, RX1, RX2 and RX3) and the four transmitters (TX0, TX1, TX2 and TX3). Use
eight SMA female-to-female (F-F) adapters (

Figure 1-5

) to connect the transmit and receive

cables as shown in

Figure 1-6

and as detailed below:

•

TX0_P

→

SMA F-F Adapter

RX0_P

•

TX0_N
