Figure 31: Timing for Power-up Reset
1 = PLL_RST_ hold time (0ns)
— PLL_RST_ can be released once the PCLK and power are stable
2 = PURST_ hold time (150us)
— PURSTI_ must be held after negation of PLL_RSTI_ to make sure the PLL is locked
3 = Assertion of SRSTO (200ms)
— Minimum assertion of SRSTO output (as required by the American National
to the PCLK frequency
Standard for VME64)
