DS1099

Low-Frequency Dual EconOscillator

Industry's Tightest Tolerance, All-Silicon, Dual Clock Oscillator


Please check latest availability status for a specific part variant.

Description

The DS1099 is a low-cost, low-power, low-frequency silicon oscillator that generates two square-wave outputs with frequencies between 0.25Hz and 1.048MHz. Individual output enables allow both outputs to be enabled/disabled independently. Both outputs are capable of sinking 16mA, allowing them to directly interface to light-emitting diodes (LEDs) as well as other external circuitry. The DS1099 operates over a wide supply voltage, making it suitable for both 3V and 5V systems. The device is shipped from the factory custom programmed and calibrated, ready to be inserted into the end application.

Contact the factory for custom frequencies or requirements.
