considerable flexibility for frequency synthesis, allowing real-time
variation of the PLL frequency and delay. The rest of the device is
functional while reconfiguring the PLL.
See the
the Stratix II GX Device Handbook for more information on Stratix II GX
PLLs.
Stratix II GX devices include a diode-connected transistor for use as a
temperature sensor in power management. This diode is used with an
external digital thermometer device. These devices steer bias current
through the Stratix II GX diode, measuring forward voltage and
converting this reading to temperature in the form of an 8-bit signed
number (7 bits plus 1 sign bit). The external device’s output represents the
junction temperature of the Stratix II GX device and can be used for
intelligent power management.
The diode requires two pins (tempdiodep and tempdioden) on the
Stratix II GX device to connect to the external temperature-sensing
device, as shown in
passive element and therefore can be used before the Stratix II GX device
is powered.
