silicon oscillators with a frequency error less than 0.09%.
For each oscillator, the user can select one of 8 frequen-
cies between 32.768kHz and 8.192MHz. Based on a fixed
master oscillator frequency, internal frequency dividers
between 1 and 128 provide the 8 different frequencies.
The LTC6930 requires no external components other than
power supply bypass capacitors. Requiring only a single
1.7V to 5.5V supply enables operation from a single Li-Ion
cell or 2 AA alkaline cells.
The LTC6930 features a proprietary control architecture
that allows for ultralow power operation while maintaining
industry leading accuracy and jitter specifications. The
exceptionally fast start-up time, combined with the low
power consumption, is ideal for battery operated applica-
tions with frequent power-up cycles.
Any frequency from 32.768kHz to 8.192MHz can be pro-
vided by the factory. Minimum order sizes apply for custom
frequencies. Please consult LTC Marketing for details.

may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
LTC6930C is guaranteed functional over the operating range of
–40°C to 85°C.
Note 3:
The LTC6930C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6930C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6930I is guaranteed to meet
specified performance from –40°C to 85°C. The LTC6930H is guaranteed
to meet specified performance from –40°C to 125°C. The LTC6930MP is
guaranteed to meet specified performance from –55°C to 125°C.
Note 4:
Frequency accuracy and frequency drift are defined as deviation
from the nominal frequency or the nominal frequency divided by the
integer set through the DIV pins for each part. The nominal frequency for
the LTC6930 family of parts are defined as follows:
LTC6930-4.19
f
NOM
= 4.194304MHz
LTC6930-5.00
f
NOM
= 5.000000MHz
LTC6930-7.37
f
NOM
= 7.372800MHz
LTC6930-8.00
f
NOM
= 8.000000MHz
LTC6930-8.19
f
NOM
= 8.192000MHz
Note 5:
Long-term drift of silicon oscillators is primarily due to the
movement of ions and impurities within the silicon and is tested at 30°C
under otherwise nominal operating conditions. Long-term drift is specified
as ppm/√kHr due to the typically non-linear nature of the drift. To calculate
drift for a set time period, translate that time into thousands of hours,
take the square root and multiply by the typical drift number. For instance,
a year is 8.77kHr and would yield a drift of 89ppm at 30ppm/√kHr. Drift
without power applied to the device may be approximated as 1/10th of the
drift with power, or 3ppm/√kHr for a 30ppm/√kHr device.
