DESCRIPTION
The LTC
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.
