LTC6990 Datasheet PDF

Linear Technology LTC6990

The LTC6990 is part of the TimerBlox® family of versatile silicon timing devices. The output frequency is determined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 128. A single resistor, RSET, programs the LTC6990’s internal master oscillator frequency.
