for the number of channels each device supports.
For high-speed source synchronous interfaces such as POS-PHY 4,
Parallel RapidIO, and HyperTransport, the source synchronous clock rate
is not a byte- or SERDES-rate multiple of the data rate. Byte alignment is
necessary for these protocols since the source synchronous clock does not
provide a byte or word boundary since the clock is one half the data rate,
not one eighth. The Stratix II device’s high-speed differential I/O
circuitry provides dedicated data realignment circuitry for user-
controlled byte boundary shifting. This simplifies designs while saving
ALM resources. You can use an ALM-based state machine to signal the
shift of receiver byte boundaries until a specified pattern is detected to
indicate byte alignment.
Fast PLL & Channel Layout
The receiver and transmitter channels are interleaved such that each I/O
bank on the left and right side of the device has one receiver channel and
one transmitter channel per LAB row.
