Philips Semiconductors Product specification Programmable ripple counter with oscillator; 3-state Typical Crystal Oscillator In Fig.13, R2 is the power limiting resistor. For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large. A practical value for R2 is 2.2 kΩ. The oscillator has been designed to operate over a wide frequency spectrum, for quartz crystals operating in the fundamental mode and in the overtone mode.
