This section provides information about the high-speed I/O standards and the HSSI
input reference clock supported in Cyclone IV devices.
Cyclone IV GX devices support the same I/O features for GPIOs with additional new
features where current I/O banks 3A and 8A consist of dual-purpose clock input pins
(CLKIN) and 3B and 8B consist of dedicated CLKIN that can be used to support the
high-speed transceiver input reference clock (REFCLK) features on top of the
general-purpose clock input function. I/O banks 3B and 8B are dedicated to high-
speed transceiver input REFCLK only.
The EP4CGX15, EP4CGX22, and EP4CGX30 devices contain two pairs of
CLKIN/REFCLK pins located in I/O banks 3A and 8A. I/O banks 3B and 8B are not
available in EP4CGX15, EP4CGX22, and EP4CGX30 devices. The EP4CGX50,
EP4CGX75, EP4CGX110, and EP4CGX150 devices have a total of four pairs of
CLKIN/REFCLK pins located in I/O banks 3A, 3B, 8A, and 8B. I/O banks 3B and 8B
can also support single-ended clock inputs. For more information about the
CLKIN/REFCLK pin location, refer to
page
The CLKIN/REFCLK pins are powered by dedicated V
and V
different power level requirements in the same bank for GPIO.
