Note: The stabilization time varies depending on the crystal, resonator or feedback network
used. See Table 115 for transconductance values to compute oscillator stabilization times.
Figure 27 displays a recommended configuration for connection with an external funda-
mental-mode, parallel-resonant crystal operating at 20 MHz. Recommended 20 MHz crys-
tal specifications are provided in Table 114. Printed circuit board layouts must add no
more than 4 pF of stray capacitance to either the XIN or XOUT pins. If oscillation does not
occur, reduce the values of capacitors C1 and C2 to decrease loading.
