Quick Detail:
17MHz to 170MHz Resistor Set SOT-23 Oscillator
Description:
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 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.
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:
For higher accuracy, fixed frequency versions that include
an internal frequency-setting resistor, see the LTC6905-
XXX Series datasheet.
