Notes to Table 1–18:
(1) For an explanation of terms used in Table 1–18, refer to “Transmitter Output Waveform” in “Glossary” on page 1–27.
(2) VIN range: 0 V ≤VIN ≤1.85 V.
(3) RL range: 90 ≤RL ≤110 Ω.
(4) LVPECL input standard is only supported at clock input. Output standard is not supported.
(5) No fixed VIN , VOD , and VOS specifications for BLVDS. They are dependent on the system topology.
(6) Mini-LVDS, RSDS, and PPDS standards are only supported at the output pins for Cyclone III devices.
Power Consumption
You can use the following methods to estimate power for a design:
■
the Excel-based EPE.
■
the Quartus II PowerPlay power analyzer feature.
The interactive Excel-based EPE is used prior to designing the device to get a
magnitude estimate of the device power. The Quartus II PowerPlay power analyzer
provides better quality estimates based on the specifics of the design after place-and-
route is complete. The PowerPlay power analyzer can apply a combination of user-
entered, simulation-derived, and estimated signal activities which, combined with
detailed circuit models, can yield very accurate power estimates.
f
For more information about power estimation tools, refer to the Early Power Estimator
User Guide and the PowerPlay Power Analysis chapter in volume 3 of the Quartus II
Handbook.
