Skyworks SKY73121-11 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 SKY73121-11 VCO/Synthesizer is a key building block for highperformance 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 SKY73121-11. The input clock frequency is divided down by programmable dividers (1 to 8) for the synthesizer. The phase detector can operate at a maximum speed of 26 MHz, which allows better phase noise due to the lower division value. The SKY73121-11 VCO/Synthesizer is provided in a compact, 38-pin Multi-Chip Module (MCM). The device package and pinout are shown in Figure 1. A functional block diagram is shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
