SKY73103: 1460-1665 MHz High Performance
VCO/Synthesizer With Integrated Switch
Applications
•
2G, 2.5G, and 3G base station transceivers:
−
GSM, EDGE, CDMA, WCDMA
•
General purpose RF systems
Description
Skyworks SKY73103 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 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. 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 SKY73103 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.
