The LTC6900IS5#PBF is a Low Power 1kHz to 20MHz Resistor Set 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 2.7 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 10kR to 2MR 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).
