DESCRIPTION

32.768kHz to 8.192MHz

Precision µPower Oscillators

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 ultra-low power operation while maintain-

ing 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.
