Ceramic oscillator

(OSC

1, OSC 2)

OSC

Ceramic

GND

Ceramic oscillator: CSA4.00MG (Murata)

f = 1 MΩ ±20%

1 = C2 = 30 pF ±20%

Crystal oscillator

(OSC

1, OSC 2)

OSC

Crystal

GND

OSC1

OSC2

f = 1 MΩ ±20%

1 = C2 = 10 to 22 pF ±20%

Crystal: Equivalent to circuit shown below

0 = 7 pF max.

S = 100 Ω max.

Notes: 1. Since the circuit constants change depending on the crystal or ceramic oscillator and stray

capacitance of the board, the user should consult with the crystal or ceramic oscillator

manufacturer to determine the circuit parameters.

2. Wiring among OSC

1, OSC 2, and elements should be as short as possible, and must not cross

other wiring (see figure 16).
