3.0 Application Information
3.1 SYSTEM LEVEL DIAGRAM
The following shows the LMK300xx in a typical application. In this setup the clock may be multiplied, reconditioned, and redis-
tributed. The first and second pole of the loop filter are external. The third and fourth poles are integrated.

FIGURE 1. Typical Application
3.2 BIAS PIN
To properly use the device, bypass Bias (pin 36) with a low leakage 1 µF capacitor connected to Vcc. This is important for low
noise performance.
3.3 LDO BYPASS
To properly use the device, bypass LDObyp1 (pin 9) with a 10 µF capacitor and LDObyp2 (pin 10) with a 0.1 µF capacitor.
