Probe Leads
Actel Silicon Explorer II ships with a replaceable target cable assembly
(TCA-8020A) that interfaces Silicon Explorer II with your target system.
To connect Silicon Explorer II, align the short red wire on the TCA-
8020 with the red dot on the case and fully insert the 2mm header. The
contacts on the TCA-8020 accept standard 0.025" round or square test
accessories.
Connect any of Silicon Explorer IIs 18-channel leads to the desired
target signals using standard test accessories. For synchronous
sampling, connect the CLKIN lead to the target clock, which requires a
continuous signal. If the clock is greater than 20 MHz, connect the CLK
GND (twisted pair) to a ground point near the CLK lead.
Connect the probe leads by attaching one of two supplied cable
assemblies.
One 16-pin cable assembly terminates in individual 0.025 connectors
that connect to 0.025 headers or microclips according to the labels on
the wires. The other assembly interfaces directly to the target board
with a 16-pin header when you install the target according to the pin-
out shown in Figure 1-1.
