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. T
