Clock circuit that multiplies input frequency by 2

[scchan107]

I wonder is any circuit capable of multiply a input signal's frequency by 2? Behave as opposite of clock divider.

Re: Clock Multiplier?

ya there are frequency multiplier circuits too present... it often uses the reverse idea of frequency divider.....

Some times you use the time delay in your logic gate to multiply input frequency...

Clock Multiplier?

I can think of a few options off the top:

1. You can use pulse generators to generate a clock on every rising/falling edge to get 2x clock.
2. You can combine lower frequency clocks that has phase offsets to generate faster clocks, if phase offset clocks are available.
3. You can use DLLs to generate the phase offset clocks and combine to generate faster clocks.
4. You can use PLL to generate faster clocks.

Clock Multiplier?

I think U want to implement circuite like DDR.
