R1 = 120 kΩ, R2 = 47 Ω, C1 = 30 pF Crystal oscillator frequency XTALCK0 = 16.9344 MHz R3 = 7.5 kΩ, R4 = 200 Ω, R5 = 10 kΩ, C3 = 0.1 µF C4 = 0.1 µF, C5 = 0.002 µF to 0.01 µF Note: The values listed above for R3, R4, R5, and C3 also apply when the XTALKC0 frequency is 33.8688 MHz.

Applications must be designed so that the analog V

and VSSpower supply system is completely independent of the

logic system power supply and is not affected by the logic system power supply fluctuation in any way.

Note: Since the exact values of these components will vary depending on the characteristics of the printed circuit board

used and other factors, consult the manufacturer of the crystal element when designing the oscillator circuit.
