5.4 Clock Circuitry
The DE2-70 board includes two oscillators that produce 28.86 MHz and 50 MHz clock signals.
Both two clock signals are connected to the FPGA that are used for clocking the user logic. Also,
the 28.86 MHz oscillator is used to drive the two TV decoders. The board also includes an SMA
connector which can be used to connect an external clock source to the board. In addition, all these
clock inputs are connected to the phase lock loops (PLL) clock input pin of the FPGA allowed users
can use these clocks as a source clock for the PLL circuit.
The clock distribution on the DE2-70 board is shown in Figure 5.8. The associated pin assignments
for clock inputs to FPGA I/O pins are listed in Table 5.5.
