General Description

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 require-

ments.
