This input can be single-ended or differential. If you are using a differential I/O standard, then two CLK pins are
used. LVDS input is supported via the secondary function of the dedicated CLK pins. For example, the CLK0 pin’s
secondary function is LVDSCLK1p and the CLK1 pin’s secondary function is LVDSCLK1n. If a differential I/O
standard is assigned to the PLL clock input pin, the corresponding CLK(n) pin is also completely used. The

This counter output is shared between a dedicated external clock output I/O and the global clock network.

Devices chapter in Volume 1 of the Cyclone II Device Handbook.
The Cyclone II embedded memory consists of columns of M4K memory
blocks. The M4K memory blocks include input registers that synchronize
writes and output registers to pipeline designs and improve system
performance. The output registers can be bypassed, but input registers
cannot.
