Transmitter, receiver, and input reference clock pins of high-speed transceivers use the PCML I/O standard.
For transmitter, receiver, and reference clock I/O pin specifications, refer to Table 2–20 on page 2–14.

Notes to Table 2–19:
(1) The 1.4-V and 1.5-V PCML transceiver I/O standard specifications are described in “Transceiver Performance Specifications” on page 2–14.
(2) RL range: 90 ≤ RL ≤ 110 Ω
Power Consumption
Altera offers two ways to estimate power consumption for a design—the Excel-based
Early Power Estimator (EPE) and the Quartus® II PowerPlay Power Analyzer feature.
1
You typically use the interactive Excel-based EPE before designing the FPGA 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 you
complete place-and-route. The PowerPlay Power Analyzer can apply a combination
of user-entered, simulation-derived, and estimated signal activities that, when
combined with detailed circuit models, yields very accurate power estimates.
f
For more information about power estimation tools, refer to the PowerPlay Early Power
Estimator User Guide and the PowerPlay Power Analysis chapter in the Quartus II
Handbook.
