Notes to
(1) The clock networks and clock control block locations apply to all EP4CGX15, EP4CGX22, and EP4CGX30 devices except EP4CGX30 device in F484
(2) PLL_1 and PLL_2 are multipurpose PLLs while PLL_3 and PLL_4 are general purpose PLLs.
(3) There are five clock control blocks on each side.
(4) PLL_4 is only available in EP4CGX22 and EP4CGX30 devices in F324 package.
(5) The EP4CGX15 device has two DPCLK pins on three sides of the device: DPCLK2 and DPCLK5 on bottom side, DPCLK7 and DPCLK8 on the
(6) Dedicated clock pins can feed into this PLL. However, these paths are not fully compensated.
