The oscillator configuration allows design of either RC or crystal oscillator circuits. The oscillator may HEF4060B MSI be replaced by an external clock signal at input RS. The counter advances on the negative-going transition of RS. A HIGH level on MR resets the counter (O3 to O9 and O11 to O13 = LOW), independent of other input conditions. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. Fig.1 Functional diagram.

January 1995 5 Philips Semiconductors Product specification 14-stage ripple-carry binary counter/divider and oscillator Timing component limitations The oscillator frequency is mainly determined by RtCt, provided Rt << R2 and R2C2 << RtCt. The function of R2 is to minimize the influence of the forward voltage across the input protection diodes on the frequency. The stray capacitance C2 should be kept as small as possible. In consideration of accuracy, Ct must be larger than the inherent stray capacitance. Rt must be larger than the LOCMOS `ON' resistance in series with it, which typically is 500 at VDD = 5 V, 300 at VDD = 10 V and 200 at VDD = 15 V. The recommended values for these components to maintain agreement with the typical oscillation formula are: Ct 100 pF, up to any practical value, 10 k Rt 1 M. Typical crystal oscillator circuit In Fig.5, R2 is the power limiting resistor. For starting and maintaining oscillation a minimum transconductance is necessary.
