Ceramic oscillator: CSB400P22 (Murata),

CSB400P (Murata)

f = 1 MΩ ± 20%

1 = C2 = 220 pF ± 5%

Ceramic oscillator: CSB800J122 (Murata),

CSB800J (Murata)

f = 1 MΩ ± 20%

1 = C2 = 220 pF ± 5%

Ceramic oscillator: CSA2.00MG (Murata)

f = 1 MΩ ± 20%

1 = C2 = 30 pF ± 20%

Ceramic oscillator: CSA4.00MG (Murata)

f = 1 MΩ ± 20%

1 = C2 = 30 pF ± 20%

Ceramic oscillator: CSA3.58MG (Murata)

f = 1 MΩ ± 20%

1 = C2 = 30 pF ± 20%

Notes: 1. Since the circuit constants change depending on the ceramic oscillator and stray capacitance of

the board, the user should consult with the 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 18).
