2014-07-04 Thread Roger Quadros
After clarification from the hardware team it was found that this 1.8V PHY supply can't be switched OFF when SoC is Active. Since the PHY IPs don't contain isolation logic built in the design to allow the power rail to be switched off, there is a very high risk of IP reliability and additional lea
