Introduction

The LTC6900 is a precision low power oscillator that is extremely easy to use and occupies very little PC board space. It is a lower power version of the LTC1799.

The output frequency, fOSC, of the LTC6900 can range from 1kHz to 20MHz—programmed via an external resistor, RSET, and a 3-state frequency divider pin, as shown in Figure 485.1.
