PLL1 (System)

The figure below shows the PLL1 circuit. Place the

decoupling capacitor in the terminal neighborhood on the

board, and keep low noise by apart from other power supply

lines.

66. C4: refers to the part of mounting on the catalog of our company (CV−B S Series).

67. appropriate value for Fref

≥ 32.768 kHz.

68. appropriate value for Fref

≥ 1 Mhz.

69. Use R2 basically by unmounting.

The characteristic of PLL might be improved by mounting R2. Prepare the wire pattern.

70. The values of parts are for reference. There is a possibility that the adjustment is needed according to the situation of the set.

71. Connect with decoupling capacitor in the terminal neighborhood on the board, and keep low noise by apart from other power supply lines.
