Modes of Operation of the AEQ
Depending on the value you set for reconfig_mode_sel[3:0], the AEQ has three
modes of operation:
■
■
■
You are allowed to switch between these modes dynamically.
The AEQ comes out of standby mode as soon as the value on reconfig_mode_sel
is changed to another mode of the AEQ control modes. After the AEQ goes into
powerdown mode and comes out, it does not remember the converged equalization
value. By design, the AEQ starts at the maximum equalization value after powering
up again.
Continuous mode—The AEQ continuously monitors the frequency content of the
received signal and adapts to it by providing dynamically changing equalizer
settings to the Stratix IV GX and GT receiver. This mode is available on one
channel or all channels of the receiver. The reconfig_mode_sel[3:0] = 1000 in
this mode.
One-time mode—The AEQ finds a stable setting of the receiver equalizer and
locks that value. Once locked, the equalizer values are no longer changed. This
mode is available in one channel or all channels of the receiver. The
reconfig_mode_sel[3:0] = 1001 in this mode.
Powerdown mode—In this mode, the AEQ of the specific channel is placed in
standby mode. This mode is available in one channel or all channels of the
receiver. The reconfig_mode_sel[3:0] = 1010 in this mode.
