Figure 7. Synthesizer Loop Filter Schematic
Note:
The PLL loop filter can be designed to optimize the phase noise around the carrier.
Three configurations can be suggested, regarding the application and channel spacing:
- Narrow band: (14.7 k + 2.2 nF) // 220 pF
- Typical: (3.3 k + 5.6 nF) // 560 pF
- High datarates: (10 k
