For high-speed source synchronous interfaces such as POS-PHY 4 and the
Parallel RapidIO standard, the source synchronous clock rate is not a
byte- or SERDES-rate multiple of the data rate. Byte alignment is
necessary for these protocols because 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 GX 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 and Channel Layout
The receiver and transmitter channels are interleaved such that each I/O
bank on the left side of the device has one receiver channel and one
transmitter channel per LAB row.
