2.3. Supply Voltage Circuitry
The TPS-1 works with three operating voltages: VDD15 (1.5 V), VDD33 (3.3 V, IO) and VDD10 (1.0 V, core). Additionally, the on-chip PLL for the
device clock generation requires a supply called PLL_AVDD (1.0 V), which is typically a filtered version of VDD10. The integrated PHYs of the
TPS-1 require additional filtered operating voltages.
