Микросхемы и комплектующие IC LTC6930HMS8-7.37#PBF

The LTC6930HMS8-7.37#PBF is a very low-power precision Silicon Oscillator with a frequency error less than 0.09%. For each oscillator, the user can select one of 8 frequencies 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 1.7 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 applications with frequent power-up cycles.
