Switching Characteristics

This section provides performance characteristics of Stratix III core and periphery

blocks for commercial grade devices.

These characteristics can be designated as Preliminary and Final and each

designation is defined below.

Preliminary

—Preliminary characteristics are created using simulation results, process

data, and other known parameters.

Final

—Final numbers are based on actual silicon characterization and testing. These

numbers reflect the actual performance of the device under worst-case silicon process,

voltage, and junction temperature conditions. The upper-right hand corner of a table

shows the designation as Preliminary or Final.

Core Performance Specifications

These sections describe the Clock Tree, PLL, digital signal processing (DSP),

TriMatrix, and Configuration and JTAG specifications.

Clock Tree Specifications

Table 1–19 lists the clock tree performance specifications for the logic array, DSP

blocks, and TriMatrix Memory blocks for Stratix III devices.

PLL Specifications

Table 1–20 lists the Stratix III PLL specifications when operating in both the

commercial junction temperature range (0 to 85° C) and the industrial junction

temperature range (-40 to 100° C), except for EP3SL340, EP3SE260, and EP3SL200

devices in the I4L ordering code, where the industrial junction temperature range is

from 0° C to 100° C, regardless of supply voltage. Refer to the figure in “PLL

Specifications” in “Glossary” on page 1–326 for the PLL block diagram.
