Switching Characteristics
Switching Characteristics
This section provides performance characteristics of Cyclone V core and periphery
blocks for commercial grade devices.
These characteristics can be designated as preliminary or final.
■
■
Preliminary characteristics are obtained using simulation results, process data,
and other known parameters. The title of these tables show the designation as
“Preliminary.”
Final numbers are based on actual silicon characterization and testing. The
numbers reflect the actual performance of the device under worst-case silicon
process, voltage, and junction temperature conditions. There are no designations
on finalized tables.
Transceiver Performance Specifications
This section describes transceiver performance specifications.
Table 2–20 lists the Cyclone V GX transceiver specifications.
