Interface Implementation in Stratix & Stratix GX Devices
The 16-bit full-duplex LVDS implementation of the framer part of the
SFI-4 interface is shown in
synchronous interfacing and LVDS differential signaling up to 840 Mbps.
Stratix devices have embedded SERDES circuitry for serial and parallel
data conversion.
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.
The fast PLL enables 622.08 Mbps data transmission by transmitting and
receiving a differential clock at rates of up to 645 MHz. The clocks
required in the SERDES for parallel and serial data conversion can be
configured from the received RXCLK (divided down), the TXCLK_SRC
(divided down), or the asynchronous core clock. See
