Altera Transceiver PHY IP Core - Manual (Page 608)

Description
Configure the VCCA_GXB voltage for a GXB I/O pin by specifying the intended VCCA_GXB voltage for
a GXB I/O pin. If you do not make this assignment the compiler automatically sets the correct
VCCA_GXB voltage depending on the configured data rate, as follows:
• Data rate <= 6.5 Gbps: 2_5V
• Data rate > 6.5 Gbps: 3_0V.
Options
• 2_5V
• 3_0V

Analog Settings Having Global or Computed Default Values for Arria V GZ Devices
The following analog parameters have global or computed default values. You may want to optimize some
of these settings. The default value is shown in bold type. For computed analog parameters, the default
value listed is for the initial setting, not the recomputed setting. The parameters are listed in alphabetical
order.
