Dedicated Circuitry with DPA Support
Stratix II devices support source-synchronous interfacing with LVDS or
HyperTransport signaling at up to 1 Gbps. Stratix II 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. For example, a HyperTransport technology application
where the data rate is 1,000 Mbps and the clock rate is 500 MHz would
require that W be set to 2. 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 Stratix II device bypasses the SERDES block. For a J factor of 2, the
Stratix II device bypasses the SERDES block, and the DDR input and
output registers are used in the IOE.
of the Stratix II transmitter channel.
Each Stratix II 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.
