Table 3–1. Supported LVDS Data Rates
The POS-PHY Level 4 MegaCore function operates either as a receiver where data
flows from the SPI-4.2 interface to the Atlantic
data flows from the Atlantic interface to the SPI-4.2 interface.
The receiver and transmitter variations are separate building blocks in a design, with
no dependency on each other, so you select the parameters independently. For the
MegaCore function to act as a full-duplex, bidirectional transceiver, instantiate one for
each direction. Typical designs may include one or more receivers and one or more
transmitters per FPGA.
After you have generated a custom variation, you can re-open the MegaWizard
Plug-In Manager and change the parameters. However, do not change a receiver
variation to a transmitter variation, or a transmitter variation to a receiver variation,
otherwise the Quartus II software generates errors during compilation.
If your receiver design requires dynamic phase alignment (DPA), turn on Dynamic
Phase Alignment.
DPA is recommended for data rates exceeding 622 Mbps, and considered essential for
high-quality signaling above 800 Mbps, or across connectors at 700 Mbps.
DPA is only available in Stratix III, Stratix II, and Stratix GX devices.
