Implementation
The 16-bit full duplex LVDS implementation of XSBI in Stratix devices is
shown in
The source-synchronous I/O implemented in Stratix GX devices
optionally includes dynamic phase alignment (DPA). DPA automatically
and continuously tracks fluctuations caused by system variations and
self-adjusts to eliminate the phase skew between the multiplied clock and
the serial data, allowing for data rates of 1 Gbps. In non DPA mode the
I/O behaves similarly to that of the Stratix I/O. This document assumes
that DPA is disabled. However, it is simple to implement the same system
with DPA enabled to take advantage of its features. For more information
on DPA, see the Stratix GX Transceivers chapter in the Stratix GX Device
Handbook, Volume 1.
