SKY73112-11 750-850 MHz High Performance
VCO/Synthesizer With Integrated Switch
SKYWORKS SKY73112-11 Voltage-Controlled Oscillator (VCO)/Synthesizer is a fully integrated, high performance signal source for high dynamic range transceivers. The device provides ultra-fine frequency resolution, fast switching speed, and low phase noise performance for 2G, 2.5G, and 3G base station transceivers. The SKY73112-11 VCO/Synthesizer is a key building block for high-performance radio system designs that require low power and a fine step size. Reference clock generators with an output frequency up to 52 MHz can be used with the SKY73112-11. A functional block diagram is shown in Figure 1. As indicated in this diagram, the reference frequency is divided down by 1, 2, 4, or 8 in the R1 divider, depending on the value of the reference divisor input (R1). Refer to the Reference Input Divider section (page 10) for more information.
