TYPICAL APPLICATION
DESCRIPTION
TimerBlox: Voltage
Controlled Silicon Oscillator
The LTC6990 is a precision silicon oscillator with a pro-
grammable 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
masteroscillatorfrequency.Theoutputfrequencyisdeter-
mined by this master oscillator and an internal frequency
divider,NDIV,programmabletoeightsettingsfrom1to128.

, 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 resistors.
The LTC6990 includes an enable function that is synchro-
nized with the master oscillator to ensure clean, glitch-free
output pulses. The disabled output can be configured to
be high impedance or forced low.
For easy configuration of the LTC6990, download the
TimerBlox Designer tool at www.linear.com/timerblox.
