The WEAPLL400M22 is a low power integer PLL operating at a single 0.8 V power supply. This PLL has a wide programmable frequency range operation operating from 300 MHz up to 600 MHz. The VCO outputs are coming into 8 cascaded phases. The PLL needs a sourcing current of 2 uA in order to operate. In the PLL logic, scan chain has been implemented for complete IP testability.
