Figure 3–16. ALTGX and ALTPLL_RECONFIG Connection for PLL Reconfiguration Mode
Notes to
(1) <n> = (number of transceiver PLLs configured in the ALTGX MegaWizard) - 1.
(2) You must connect the pll_reconfig_done signal from the ALTGX to the pll_scandone port from ALTPLL_RECONFIG.
(3) You need two ALTPLL_RECONFIG controllers if you have two separate ALTGX instances with transceiver PLL instantiated in each ALTGX instance.

Receives the scan data input from the
ALTPLL_RECONFIG megafunction.
Used to reset the transceiver PLL
during the reset sequence. During
reset sequence, this signal is user
controlled.
After the transceiver PLL is
reconfigured, this signal is
asserted high by the
ALTPLL_RECONFIG controller. At
this time, this signal is not user
controlled.

pll_reconfig_signals
You must connect the pll_areset port of ALTGX to the
pll_areset port of the ALTPLL_RECONFIG
megafunction.
The ALTPLL_RECONFIG controller asserts the
pll_areset port at the next rising clock edge after the
pll_reconfig_done signal from the ALTGX
megafunction goes high. After the
pll_reconfig_done signal goes high, the transceiver
PLL is reset. When the PLL reconfiguration is completed,
this reset is performed automatically by the
ALTPLL_RECONFIG megafunction and is not user
controlled.
The reconfigurable transceiver PLL received the scan data
input through this port for the dynamically reconfigurable
bits from the ALTPLL_RECONFIG controller.
