TC11IB
Power Supply
The TC11IB provides an ingenious power supply concept in order to improve the EMI
behavior as well as to minimize the crosstalk within on-chip modules.
Figure 19 shows the TC11IB’s power supply concept, where certain logic modules are
individually supplied with power. This concept improves the EMI behavior by reduction
of the noise cross coupling.
