LTC6930-X.XX 32.768kHz to 8.192MHz Precision Power Oscillators FeaT DescripT n Frequency Error <0.09% Max at 25C The LTC 6930 series is a family of very low power precision n Start-Up Time <110s at All Frequencies silicon oscillators with a frequency error less than 0.09%. n 1.7V to 5.5V Single Supply Operation For each oscillator, the user can select one of 8 frequen- + n 105A Typical Supply Current at 32kHz, V = 3V cies between 32.768kHz and 8.192MHz. Based on a fixed + n 490A Typical Supply Current at 8MHz, V = 3V master oscillator frequency, internal frequency dividers + n Typical RMS Period Jitter <0.15% at V = 3V between 1 and 128 provide the 8 different frequencies. n No External Components to Set Frequency The LTC6930 requires no external components other than n 5 Options Cover 32.768kHz to 8.192MHz: power supply bypass capacitors. Requiring only a single LTC6930-4.19: 4.194304MHz N 1.7V to 5.5V supply enables operation from a single Li-Ion LTC6930-5.00: 5.000000MHz N cell or 2 AA alkaline cells. LTC6930-7.37: 7.372800MHz N The LTC6930 features a proprietary control architecture LTC6930-8.00: 8.000000MHz N that allows for ultralow power operation while maintaining LTC6930-8.19: 8.192000MHz N industry leading accuracy and jitter specifications. The Where N = 1, 2, 4, 8, 16, 32, 64, 128 exceptionally fast start-up time, combined with the low (N Determined by State of DIVA, DIVB, DIVC Pins) power consumption, is ideal for battery operated applica- n 55C to 125C Operating Temperature Range tions with frequent power-up cycles. n Tiny 2mm 3mm DFN or MS8 Package Any frequency from 32.768kHz to 8.192MHz can be pro- vided by the factory. Minimum order sizes apply for custom Ta frequencies.
