1.4.2. Internal Oscillator

Intel® MAX® 10 devices have built-in internal ring oscillator with clock multiplexers and dividers. The internal ring oscillator operates up to 232 MHz which is not accessible. This operating frequency further divides down to slower frequencies.

When the oscena input signal is asserted, the oscillator is enabled and the output can be routed to the logic array through the clkout output signal. When the oscena signal is set low, the clkout signal is constant high. You can analyze this delay using the Timing Analyzer.
