HSDI Port A Interface
1
Bank 6 of the Stratix device contains an 8-bit HyperTransport-capable port
wired to a connector that mates with several Broadcom reference boards.
The connector at J13 allows the Stratix PCI development board to connect
to other boards with a Broadcom-type HyperTransport connector.
Compatible boards include:
I/O Standard
Jumper J20 allows HSDI port A to operate at 2.5 V for the HyperTransport
interface or 3.3 V for signaling standards such as the SPI-4.2 and RapidIO
interfaces.
HSDI port A uses discrete differential receive termination resistors as
required by the HyperTransport, SPI-4.2, and RapidIO interfaces.
Reference Clock
Stratix device pin U2.AB4 receives B6_REF_CLK from HSDI port A
connector J13. This clock connects to PLL9.
Optional HSDI Port A Interface Cable
An optional HSDI port A interface cable is available from Precision
Interconnect (www.precisionint.com). Use the configuration code
023850120015NR20.
