14. Example of Application Circuit
V
Note 10: According to the diving noise of outside which receives a power supply line and GND line, etc., or jitters of the input signal, and other operating conditions (power-supply voltage, temperature conditions, etc.), the lock of PLL may separate from this product
DDX
and V
and it may become unstable.
Please determine constant value according to the characteristic of a circuit in the case of use of this product. In addition, the constant value in the example of an application circuit is for explaining operation of this product, and application, and does not offer a
guarantee of operation.
