LTC6905
17MHz to 170MHz
Resistor Set SOT-23 Oscillator
FEATURES DESCRIPTION n The LTC®6905 precision, programmable silicon oscillator is easy to use and occupies very little board space. It
requires only a single resistor to set the output frequency
from 17MHz to 170MHz with a typical frequency error of
0.5% or less. The LTC6905 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: APPLICATIONS The LTC6905 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. Operation is simple: A
single resistor, RSET, between 10k to 25k is used to set
the frequency, and an internal three-state divider (DIV
input) allows for division of the master clock by 1, 2 or 4,
providing three frequencies for each RSET value. High Frequency Precision Oscillator
