1.10.167. GXB_TX_PLL_RECONFIG_GROUP

Specifies whether GXB transceiver channels with Dynamic TX PLL Reconfiguration can be placed in the same physical GXB Quad. If the GXB transceivers have 2 dynamically reconfigured TX PLLs, the GXB transceivers are not placed into the same physical Quad when Dynamic TX PLL Reconfiguration setting is turned ON unless they are in the same TX PLL reconfig group. If the GXB transceivers have 1 dynamically reconfigured TX PLLs, GXB transceivers from 2 TX PLL reconfig groups can be placed into the same physical Quad if the logical number on the TX PLLs are different. GXB transceivers can be assigned to the same group if the following conditions are met: (1) GXB transmitters in the same group can only listen to 2 TX PLLs at one time, (2) the user must maintain proper data rates on TX PLLs according to Altera user guidelines, (3) the user must wait for pll_locked signal asserted for dynamic PLL reconfiguration completion, and the GXB receiver and transmitter will be kept in reset until the dynamic reconfiguration of both is complete.
