A high-speed, high-resolution multi-loop synthesizer is integrated. The synthesizer can
operate within two frequency bands: 400 to 480 MHz and 800 to 950 MHz. All channels
within these two bands can be selected by programming registers F0 to F3. All circuitry
is on-chip with the exception of the PLL loop filter. The phase comparison is made
thanks to a charge pump topology. The typical charge pump current is 225 µA.
Figure 2-4.
The PLL loop filter can be designed to optimize the phase noise around the carrier. A
few configurations for the application and channel spacing can be suggested.
