LTC699016990fcFor more information APPLICATIONDESCRIPTIONT imerBlox: Voltage Controlled Silicon OscillatorThe LT C 6990 is a precision Silicon oscillator with a pro-grammable frequency range of 488Hz to 2 MHz. 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 single resistor, RSET, programs the LTC6990 s internal master oscillator frequency. The output frequency is deter-mined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 128. fOUT=1 MHzNDIV 50k RSET, NDIV= 1, 2, 4 ..128 Optionally, a second resistor at the SET input provides linear Voltage control of the output frequency and can be used for frequency modulation. A narrow or wide VCO tuning range can be configured by the appropriate selec-tion of the two LTC6990 includes an enable function that is synchro-nized with the master oscillator to ensure clean, glitch-free output pulses.
