PLL Planning

and Utilization

Stratix II devices support enhanced PLLs and fast PLLs. HardCopy II

devices also support enhanced PLLs and fast PLLs, but with two

variations:

■

HardCopy II devices have a different number of PLLs than Stratix II

devices.

■

HardCopy II devices may support fewer I/O standards for clock

inputs and outputs. This is explained in the I/O standards support

section later in this chapter.

Table 8–18 shows which PLLs each HardCopy II and Stratix II device

supports. The Stratix II reference columns are divided based on package,

not density. Figures 8–3 to 8–5 show PLL number designations. The

Stratix II devices support 6 or 12 PLLs depending on the package offering,

and not the device density. The HardCopy II PLLs are not removed

symmetrically from all four sides. In general, fast PLLs are removed from

sides that do not support high speed IOEs since the primary use of the fast

PLL on the sides is for high speed I/O interface functions.

Notes to Table 8–17:

(1)

Stratix II M4K blocks support .mif file loading.

(2)

Stratix II memory blocks remain powered up even when not used.
