Typical Application
Description
The LTC®6994 is a programmable delay block with a range of 1μs to 33.6 seconds. The LTC6994 is part of the TimerBlox® family of versatile silicon timing devices.
A single resistor, RSET , programs an internal master oscillator frequency, setting the LTC6994’s time base. The input-to-output delay is determined by this master oscillator and an internal clock divider, NDIV , programmable to eight settings from 1 to 221:
