The DS1099 is a low-cost, low-power, low-frequency
silicon oscillator that generates two square-wave out-
puts 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.
