Clock Networks in Stratix III Devices
6–2
Stratix III Device Handbook, Volume 1
Stratix III devices have up to 32 dedicated single-ended clock pins or
16 dedicated differential clock pins (CLK[0:15]p and CLK[0:15]n)
that can drive either the GCLK or RCLK networks. These clock pins are
arranged on the four sides of the Stratix III device, as shown in
Figures 6–1
Global Clock Networks
Stratix III devices provide up to 16 GCLKs that can drive throughout the
entire device, serving as low-skew clock sources for functional blocks like
adaptive logic modules (ALMs), digital signal processing (DSP) blocks,
TriMatrix memory blocks, and PLLs. Stratix III device I/O elements

There are 64 RCLKs in EP3SL50, EP3SL70, EP3SL110, EP3SL150, EP3SE50,
EP3SE80, and EP3SE110 devices. There are 88 RCLKs in EP3SL200, EP3SE260,
and EP3SL340 devices.
There are a total of 56 PCLKs in EP3SL50, EP3SL70, and EP3SE50 devices. There
are 88 PCLKs in EP3SL110, EP3SL150, EP3SL200, EP3SE80, and EP3SE110
devices. There are 112 PCLKs in EP3SE260 and 116 PCLKs in the EP3SL340
device.
There are 32 GCLKs/RCLKs per quadrant in EP3SL50, EP3SL70, EP3SL110,
EP3SL150, EP3SE50, EP3SE80, and EP3SE110 devices. There are 38
GCLKs/RCLKs per quadrant in EP3SL200, EP3SE260, and EP3SL340 devices.
There are 80 GCLKs/RCLKs per entire device in EP3SL50, EP3SL70, EP3SL110,
EP3SL150, EP3SE50, EP3SE80, and EP3SE110 devices. There are 104
GCLKs/RCLKS per entire device in EP3SL200, EP3SE260, and EP3SL340
devices.
