7.2.2.1 Design Requirements

The square-wave period is determined by the RC time constant of the capacitor C1 and resistor R4. The maximum frequency is limited by propagation delay of the device and the capacitance load at the output. The low input bias current allows a lower capacitor value and larger resistor value combination for a given oscillator frequency, which may help to reduce BOM cost and board space. R4 must be over several kilo-ohms to minimize loading the output.
