Configuring Stratix II and Stratix II GX Devices
FPP Configuration Using a MAX II Device as an External Host
FPP configuration using compression and an external host provides the
fastest method to configure Stratix II and Stratix II GX devices. In the FPP
configuration scheme, a MAX II device can be used as an intelligent host
that controls the transfer of configuration data from a storage device, such
as flash memory, to the target Stratix II or Stratix II GX device.
Configuration data can be stored in RBF, HEX, or TTF format. When
using the MAX II devices as an intelligent host, a design that controls the
configuration process, such as fetching the data from flash memory and
sending it to the device, must be stored in the MAX II device.
1 If you are using the Stratix II or Stratix II GX decompression
and/or design security feature, the external host must be able to
send a DCLK frequency that is 4× the data rate.
The 4× DCLK signal does not require an additional pin and is sent on the
DCLK pin. The maximum DCLK frequency is 100 MHz, which results in a
maximum data rate of 200 Mbps. If you are not using the Stratix II or
Stratix II GX decompression or design security features, the data rate is
8× the DCLK frequency.
Figure 7–3 shows the configuration interface connections between the
Stratix II or Stratix II GX device and a MAX II device for single device
configuration.

Note to Figure 7–3:
(1) The pull-up resistor should be connected to a supply that provides an acceptable
input signal for the device. V_CC should be high enough to meet the V_IH
specification of the I/O on the device and the external host.
