I am seeking a chip which can add a programmable phase delay on a pulse signal from a controller. Just to add a delay time on both rising edge and falling edge. By using multiple chips to get several pulse signals with different delay time. The pulse width after delay must match very well (width error should be less than 20ns) and the delay time can be programmed in the range of 1us to 10us.
It is found that the AD9500 is suitable for my application but I am told that this chip is obsolete. So, can anyone tell me which part can be recommended to replace it?
Appreciated for your help!
