No, not on the ZC702 board rev. C.
The Zynq-7000 EPP split power domain scheme provides designers with the flexibility to save power by utilizing the programmable logic only when needed by their system. The PS can use the PMBUS to access the POWER controllers and power-off the PL power supplies (VCCINT, VCCBRAM, VCCAUX, VADJ and VCC2v5_PL). The problem is that on the ZC702, VCCAUX is connected to VCC1v8 that provides power to U65 thatoutputs thePS_CLK.
