10 Application Example
* : See section 8.3.1.
Decoupling capacitors (0.1 F) for the power supply pin, should be located as close to the LC89052T as possible. Use
There are no constraints on the NC pin configuration. IC operation is not affected by leaving them open or by holding
ceramic capacitors with good high frequency characteristics as the decoupling capacitors. Use a capacitor with a
minimal thermal coefficient for the PLL loop filter capacitor.
