Stratix Device Handbook, Volume 2
The enhanced and fast PLL circuits in Stratix and Stratix GX devices
contain analog components embedded in a digital device. These analog
components have separate power and ground pins to minimize noise
generated by the digital components. Both Stratix and Stratix GX
enhanced and fast PLLs use separate VCC and ground pins to isolate
circuitry and improve noise resistance.
VCCA & GNDA
Each enhanced and fast PLL uses separate VCC and ground pin pairs for
their analog circuitry. The analog circuit power and ground pin for each
PLL is called PLL<PLL number>_VCCA and PLL<PLL number>_GNDA.
Connect the VCCA power pin to a 1.5-V power supply, even if you do not
use the PLL. Isolate the power connected to VCCA from the power to the
rest of the Stratix and Stratix GX device or any other digital device on the
board. You can use one of three different methods of isolating the VCCA
pin: separate V
V
Separate V
A mixed signal system is already partitioned into analog and digital
sections, each with its own power planes on the board. To isolate the
VCCA pin using a separate V
analog 1.5-V power plane.
Partitioned V
Fully digital systems do not have a separate analog power plane on the
board. Because it is expensive to add new planes to the board, you can
create islands for VCCA_PLL.
