LTC1799

1kHz to 33MHz

Resistor Set SOT-23 Oscillator

DESCRIPTIO

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

SET

). The LTC1799 has been designed for high accuracy

operation (≤1.5% frequency error) without the need for

external trim components.

The LTC1799 operates with a single 2.7V to 5.5V power

supply and provides a rail-to-rail, 50% duty cycle square

wave output. The CMOS output driver ensures fast rise/fall

times and rail-to-rail switching. The frequency-setting

resistor can vary from 3k to 1M to select a master

oscillator frequency between 100kHz and 33MHz (5V

supply). The three-state DIV input determines whether the

master clock is divided by 1, 10 or 100 before driving the

output, providing three frequency ranges spanning 1kHz

to 33MHz (5V supply). The LTC1799 features a proprietary

feedback loop that linearizes the relationship between

SET

and frequency, eliminating the need for tables to

calculate frequency. The oscillator can be easily pro-

grammed using the simple formula outlined below:
