The ALTPLL_RECONFIG block handles the programming of the ROM contents into
the transceiver megafunction. The ROM holds the transceiver setting information for
3G-SDI video standard. As the setup for SD-SDI is similar to 3G-SDI, only two
settings are required: one for SD-SDI and 3G-SDI, and one for HD-SDI.
The reconfiguration control logic selects the correct transceiver setting and also
provides the handshaking between the SDI MegaCore function and the
ALTPLL_RECONFIG block. The PLL reprogramming signals for the transceiver are
brought to the top-level interface of the SDI MegaCore function. This interface is only
available when you select Use PLL reconfiguration for transceiver dynamic
reconfiguration option in the SDI parameter editor. You must connect this interface
only to the ALTPLL_RECONFIG block.
