Probe Description
The ICE50 probe is the link between the flex cable going out from the POD and the Per-
sonaliy Adapter that fits into the target application. The main purpose of the probe is to
route all the signals from the flex cable to the appropriate pins of the personality adapter.
In addition the Probe implements current limitation on all the I/O pins in order to protect
both the target and the POD. The probe also implements proper line termination in order
to avoid ringing on high freuency signals.
The Probe contains clock driver circuitry for the ICE50, voltage polarity and short circuit
protection. Figure 3-23 show a picture of the probe and a simplified block diagram of
how the clock driver circuitry is implemented is shown in Figure 3-24 and Figure 3-25.
By putting the clock driver circuitry on the Probe (as close as possible to the target
board) the best possible emulation of the AVR clock options are achieved.
