OSC_VSS

N/A

Ground power supply input pins used for the internal logic of the analog oscillator circuitry. Used in

conjunction with the OSC_VCC pins.

Requires special power filtering circuitry. Refer to Figure 13 on page 106.

VCCPLL1

N/A

1.3-V power supply input pins used for the internal logic of the analog phase lock-loop circuitry.

Requires special power filtering circuitry. If operating at 667 MHz, this supply voltage needs to be

increased to VCC = 1.5 V. Refer to Figure 9 on page 104.

VCCPLL2

N/A

1.3-V power supply input pins used for the internal logic of the analog phase lock-loop circuitry.

Requires special power filtering circuitry. If operating at 667 MHz, this supply voltage needs to be

increased to VCC = 1.5 V. Refer to Figure 10 on page 105.

VCCPLL3

N/A

1.3-V power supply input pins used for the internal logic of the analog phase lock-loop circuitry.

Requires special power filtering circuitry. If operating at 667 MHz, this supply voltage needs to be

increased to VCC = 1.5 V. Refer to Figure 11 on page 105.
