TYPICAL APPLICATION
DESCRIPTION
Low Power, 1kHz to 20MHz
Resistor Set SOT-23 Oscillator
The LTC6900 is a precision, low power 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 LTC6900 has been designed for high
accuracy operation (≤1.5% frequency error) without the
need for external trim components.
The LTC6900 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 10kΩ to 2MΩ to select a master
oscillator frequency between 100kHz and 20MHz (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 20MHz (5V supply). The LTC6900 features a proprietary
feedback loop that linearizes the relationship between RSET
and frequency, eliminating the need for tables to calculate
frequency. The oscillator can be easily programmed using
the simple formula outlined below:
