Transmitter Output Buffer
The Arria II GX and GZ transmitter output buffers support the 1.5-V pseudo current
mode logic (PCML) I/O standard and can drive 40 inches of FR4 trace (with 50-
impedance) across two connectors.
For data rates > 3.75 Gbps, Altera recommends limiting the FR4 trace length to
15 inches.
The transmitter output buffer power supply (V
transmitter output buffers in the transceiver channels. This is set to 1.5 V in the
ALTGX MegaWizard Plug-In Manager. The common mode voltage (V
Arria II GX and GZ transmitter output buffers is 650 mV.
To improve signal integrity, the transmitter output buffer has the following additional
circuitry, which you can set in the ALTGX MegaWizard Plug-In Manager:

various receiver requirements.
Programmable pre-emphasis—Pre-emphasis boosts high frequencies in the
transmit data signal, which might be attenuated in the transmission media
because of data-dependent jitter and other intersymbol interference (ISI) effects. It
equalizes the frequency response at the receiver so the differences between the
low-frequency and high-frequency components are reduced, minimizing the ISI
effects from the transmission medium.
Programmable differential on-chip termination (OCT)—The Arria II GX and GZ
transmitter buffer includes a differential OCT of 85 (for Arria II GZ only) or
100 . The resistance is adjusted in the calibration block to compensate for
temperature, voltage, and process changes (for more information, refer to
“Calibration Block” on page
1
Pre-emphasis requirements increase as data rates through legacy backplanes
increase. Using pre-emphasis can maximize the data eye opening at the far-end
receiver.
You can set the transmitter termination setting in the ALTGX MegaWizard Plug-In
Manager or through the Quartus II Assignment Editor by setting the assignment
output termination to 85 (Arria II GZ only) or 100 on the transmitter output
buffer.
You can disable OCT and use external termination. In this case, the transmitter
common mode is tri-stated.
The Arria II GX and GZ transmitter output buffers in the transceiver block
are current-mode drivers. The resulting V
