LT1721 Pulse Generator Has 0ns to 10ns Width, 520ps Transitions

Pulse Generator Has 0ns to 10ns Width, 520ps Transitions

It is sometimes desirable to produce extremely short width pulses in response to an input trigger. Such a predictable, programmable short time interval generator has broad use in fast pulse circuitry, particularly in sampling applications. This circuit, built around a quad high speed comparator and a fast gate, has a settable 0ns to 10ns output width with 520ps, 5V transitions. Pulse width varies less than 100ps with 5V supply variations of ±5%. Minimum input trigger width is 30ns and input-output delay is 18ns
