Arria GX devices support source-synchronous interfacing with LVDS signaling at up
to 840 Mbps. Arria GX devices can transmit or receive serial channels along with a
low-speed or high-speed clock.
The receiving device PLL multiplies the clock by an integer factor W = 1 through 32.
The SERDES factor J determines the parallel data width to deserialize from receivers
or to serialize for transmitters. The SERDES factor J can be set to 4, 5, 6, 7, 8, 9, or 10
and does not have to equal the PLL clock-multiplication W value. A design using the
dynamic phase aligner also supports all of these J factor values. For a J factor of 1, the
Arria GX device bypasses the SERDES block. For a J factor of 2, the Arria GX device
bypasses the SERDES block, and the DDR input and output registers are used in the
IOE.
Each Arria GX receiver channel features a DPA block for phase detection and
selection, a SERDES, a synchronizer, and a data realigner circuit. You can bypass the
dynamic phase aligner without affecting the basic source-synchronous operation of
the channel. In addition, you can dynamically switch between using the DPA block or
bypassing the block via a control signal from the logic array.
