the primary oscillator is used as the clock source and its frequency is 7.648 GHZ. the PLL is used. in that case, the FCY)? what is TCY? show your calculation

Answer 1

To calculate the values of FCY and TCY, we need to consider the formula used to determine FCY:

FCY = (Primary oscillator frequency) / (PLL prescale value * PLL postscale value)

Here, the primary oscillator frequency is given as 7.648 GHz.

Assuming no prescale or postscale values are mentioned, we can consider their default values, which are 1.

Using the formula, we can calculate:

FCY = (7.648 GHz) / (1 * 1) = 7.648 GHz

Hence, FCY (clock frequency) is 7.648 GHz.

Now let's determine TCY (clock period):

TCY = 1 / FCY

Substituting the value we obtained for FCY:

TCY = 1 / 7.648 GHz

Converting GHz to Hz:

TCY = 1 / (7.648 x 10^9) s^-1 = 1.304 x 10^-10 seconds

Therefore, TCY (clock period) is approximately 1.304 x 10^-10 seconds.

Answer 2

are you sure these are correct answers?

Answer 3

Apologies for any confusion caused. In the absence of the PLL multiplication factor (M), it is not possible to accurately determine the values of FCY and TCY. The PLL multiplication factor plays a crucial role in adjusting the primary oscillator frequency and determining the resulting clock frequencies.

To further assist you, please provide any additional information regarding the PLL multiplication factor (M) or the specific system requirements.
