processor clock frequency Vs crystal frequency

[coolchip]

How are they different ?
Thanks!

Crystal Frequency -> multiplier/divider -> Clock Frequency

Pls correct me if I'm wrong.

In 8085 µp,the crystal used for generating freuency.but we use a jk FF in toggle
mode to generate the clock frequency.

hai

Crystal generates analog signal.
but clock generates digital signal.

 

[power-twq]

crystal frequency is reference clock.

processor clock frequency = n * reference clock(for example n = 8)

(generally, we use a PLL to generate processor clock from crystal frequency)
