Sample calculation of capacitance C1 and C2 for 5.83 MHz frequency and
inductance value of 27 µH.
5.83 (106) =

2Ï [2.7 (10â6) CT] 1/2
CT = 27.6 pF
Thus C1 = 55.2 pF and C2 = 55.2 pF.
RC Oscillator
In some cases, the Z8® CPU features an RC oscillator option. Please refer
to the speciï¬c product speciï¬cation for availability. The RC oscillator
requires a resistor across XTAL1 and XTAL2. An additional load capaci-
tor is required from the XTAL1 input to VSS pin (see Figure 21).
