Enhanced PLLs
PLL6_FBp/n
Single-ended or differential pins that can drive the fbin port for PLL 6.
PLL11_FBp/n
Single-ended or differential pins that can drive the fbin port for PLL 11.
PLL12_FBp/n
Single-ended or differential pins that can drive the fbin port for PLL 12.
PLL_ENA
Dedicated input pin that drives the pllena port of all or a set of PLLs. If you do
not use this pin, connect it to ground.
PLL5_OUT[2..0]p/n
Single-ended or differential pins driven by C[5..0] ports from PLL 5.
PLL6_OUT[2..0]p/n
Single-ended or differential pins driven by C[5..0] ports from PLL 6.
PLL11_OUT[2..0]p/n
Single-ended or differential pins driven by C[5..0] ports from PLL 11.
PLL12_OUT[2..0]p/n
Single-ended or differential pins driven by C[5..0] ports from PLL 12.
VCCA_PLL5
Analog power for PLL 5. You must connect this pin to 1.2 V, even if the PLL is not
used.
GNDA_PLL5
Analog ground for PLL 5. You can connect this pin to the GND plane on the board.
VCCA_PLL6
Analog power for PLL 6. You must connect this pin to 1.2 V, even if the PLL is not
used.
GNDA_PLL6
Analog ground for PLL 6. You can connect this pin to the GND plane on the board.
VCCA_PLL11
Analog power for PLL 11. You must connect this pin to 1.2 V, even if the PLL is not
used.
GNDA_PLL11
Analog ground for PLL 11. You can connect this pin to the GND plane on the
board.
VCCA_PLL12
Analog power for PLL 12. You must connect this pin to 1.2 V, even if the PLL is not
used.
GNDA_PLL12
Analog ground for PLL 12. You can connect this pin to the GND plane on the
board.
VCCD_PLL
Digital power for PLLs. You must connect this pin to 1.2 V, even if the PLL is not
used.
VCC_PLL5_OUT
External clock output VCCIO power for PLL5_OUT0p, PLL5_OUT0n,
PLL5_OUT1p
, PLL5_OUT1n, PLL5_OUT2p, and PLL5_OUT2n outputs from
PLL 5.
VCC_PLL6_OUT
External clock output VCCIO power for PLL6_OUT0p, PLL6_OUT0n,
PLL6_OUT1p
, PLL6_OUT1n and PLL6_OUT2p, PLL6_OUT2n outputs from
PLL 6.
VCC_PLL11_OUT
External clock output VCCIO power for PLL11_OUT0p, PLL11_OUT0n,
PLL11_OUT1p
, PLL11_OUT1n and PLL11_OUT2p, PLL11_OUT2n outputs
from PLL 11.
