Product Overview

The LTC6990CS6#TRMPBF is a voltage controlled Silicon Oscillator with a programmable frequency range of 488Hz to 2MHz. It can be used as a fixed-frequency or voltage-controlled oscillator (VCO). The LTC6990 is part of the TimerBlox® family of versatile silicon timing devices. A single resistor, RSET, programs the LTC6990's internal master oscillator frequency. The output frequency is determined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 128. When the output is disabled, it is either held low or placed in a high impedance state as dictated by the Hi-Z bit value. When power is first applied to the LTC6990 the power-on reset (POR) circuit will initiate the start-up time. The OUT pin is floated (high-impedance) during this time.
