Figure 2-2. Power Scheme for Operation With External 1.8V Supply
External 1.1V rail When external 1.1V rail is available – Connect the external 1.1V to the following
pins: VA11_PFBOUT (pin 10), VDD11 (pin 20), VA11_PFBIN1 (pin 1), VA11_PFBIN2 (pin 7),
VDD33_VA11 (pin 11) and VDD33_VD11 (pin 21) as shown in Figure 2-3:
Figure 2-3. Power Scheme for Operation With External 1.1V Supply
Lowest-power operation – When 1.1V and 1.8V supplies are already available in addition to 3.3V,
designers can take advantage of the lowest-power configuration of the TLK100. By supplying external
1.8 and 1.1V as explained above, all the internal regulators are powered down and the device is fully
driven by the external supplies giving the lowest power operation.
