I am looking for delay line IC for digital signal.
I have some signal which I want to delay in us range (0-999us) with 1 us increment
1. I have looked at DS1100-500, that is good but its only for 500ns.
I can cascade some IC in series to generate delay in us but not for large signal.
2. For us range I have checked LTC6994-2. It is good IC. Only problem is if I try to delay both edges, the input pulse width can never be less than tDELAY, otherwise no output signal is generated.
Tdelay is time set for generating delay.
e.g if set 20us delay, & I send a 1us input pulse, then IC removes it & generate no output instaed of delaying.
3. On net I have checked many IC all have delay of picosecond or nanosecond.
4. I want IC to be discrete or programmable by discrete components like LTC6994-2 set delay by selecting resistor value.
