LTC1799 1kHz to 33MHz Resistor Set SOT-23 Oscillator Features
Description
n n n
The LTC®1799 is a precision oscillator that is easy to use and occupies very little PC board space. The oscillator frequency is programmed by a single external resistor (RSET). The LTC1799 has been designed for high accuracy operation (≤1.5% frequency error) without the need for external trim components.

Alternative Methods of Setting the Output Frequency of the LTC1799 The oscillator may be programmed by any method that sources a current into the SET pin (Pin 3). The circuit in Figure 3 sets the oscillator frequency using a programmable current source and in the expression for fOSC, the resistor RSET is replaced by the ratio of 1.13V/ICONTROL. As already explained in the “Theory of Operation,” the voltage difference between V + and SET is approximately 1.13V, therefore, the Figure 3 circuit is less accurate than if a resistor controls the oscillator frequency. Figure 4 shows the LTC1799 configured as a VCO. A voltage source is connected in series with an external 10k resistor. The output frequency, fOSC, will vary with VCONTROL, that is the voltage source connected between V + and the SET pin. Again, this circuit decouples the relationship between the input current and the voltage between V+ and SET; the frequency accuracy will be degraded. The oscillator frequency, however, will monotonically increase with decreasing VCONTROL.
