Encoder Oscillator Information This oscillator operates at a frequency determined by the external RC network; i.e., f ≈ 1 2.3 RTC CTC′ (Hz) for 1 kHz ≤ f ≤ 400 kHz where: CTC′ = CTC + Clayout + 12 pF RS ≈ 2 RTC RS ≥ 20 k RTC ≥ 10 k 400 pF < CTC < 15 µF The value for RS should be chosen to be ≥ 2 times RTC. This range ensures that current through RS is insignificant compared to current through RTC. The upper limit for RS must ensure that RS x 5 pF (input capacitance) is small com- pared to RTC x CTC. For frequencies outside the indicated range, the formula is less accurate. The minimum recommended oscillation frequency of this circuit is 1 kHz. Sus- ceptibility to externally induced noise signals may occur for frequencies below 1 kHz and/or when resistors utilized are greater than 1 M Ω. Figure 10.
