C1e and C2e are the external load capacitances

(see Figure 6b). Normally, they are not needed

due to integrated load capacitances of 10 pF;

see curve (2).

(1)

C1e =C2e =22pF.

(2)

C1e =C2e = 0 pF.

(3)

C1e =C2e =12pF.

For correct function of the oscillator, the values

of R1 and C0 of the chosen resonator (quartz or

PXE) must be below the related curve lines

shown in Figure 7a. The value of the parallel

resistor R0 must be less than 47 k

Ω.

The wiring between chip and resonator should

be kept as short as possible.
