The noninverting input threshold levels are set so that
the capacitor voltage oscillates between 1/3 and 2/3 of
VCC. This requires the resistors R1a, R1b and R2 to be of
equal value. The following formula can be used to ap-
proximate the output frequency.

The timing capacitor CT will charge through diode D2 and discharge
through diode D1, allowing a variable duty cycle. The pulse width of the
signal can be programmed by adjusting the value of the trimpot. The ca-
pacitor voltage will oscillate between 1/3 and 2/3 of VCC, since all the
resistors at the noninverting input are of equal value.
