Description
Skyworks SKY73126-31 Voltage-Controlled Oscillator
(VCO)/Synthesizer is a fully integrated, high performance signal
source for base station transceivers. The device provides low
phase-noise performance for 3G base station transceivers and
general RF system applications.
The SKY73126-31 VCO/Synthesizer is a key building block for
high performance radio system designs that require low power
and low phase noise. The device provides a fixed 161.92 MHz
frequency source output. A 10 MHz or 32 MHz reference clock
frequency could be used for this device.
The integer-N Phase Locked Loop (PLL), loop filter, VCO, varactor,
frequency divider and output buffer are integrated inside the
device. An integrated 3.3 V voltage regulator provides superior
phase-noise performance. The SKY73126-31 is programmed
through a three-wire Serial Peripheral Interface (SPI).
The SKY73126-31 VCO/Synthesizer is provided in a compact,
16-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.
