Description Skyworks SKY73103-11 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 SKY73103-11 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 SKY73103-11. 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 v...
