The LTC

®6900 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 10k

Ω 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 pro-

grammed using the simple formula outlined below:
