LTC6990

TimerBlox: Voltage Controlled

Silicon Oscillator

FEATURES

DESCRIPTION

The LTC^®6990 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.

Fixed-Frequency or Voltage-Controlled Operation

Fixed: Single Resistor Programs Frequency with

<1.5% Max Error

VCO: Two Resistors Set VCO Center Frequency

and Tuning Range

Frequency Range: 488Hz to 2MHz

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.

Available in Low Profile (1mm) SOT-23 (ThinSOT™)

and 2mm × 3mm DFN Package

AEC-Q100 Qualified for Automotive Applications

APPLICATIONS

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.

Low Cost Precision Programmable Oscillator

Voltage-Controlled Oscillator

High Vibration, High Acceleration Environments
