RFMD RFFC5071 芯片, 射频合成器/压控振荡器/混频器, 6GHZ, 32QFN
The is a re-configurable Frequency Conversion Device with integrated fractional-N phased locked loop PLL synthesizer, voltage controlled oscillator VCO and either one or two high linearity mixers. The fractional-N synthesizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The device can be configured to work as signal sources by bypassing the integrated mixers. Device programming is achieved via a simple 3-wire serial interface. In addition, a unique programming mode allows up to four devices to be controlled from a common serial bus. This eliminates the need for separate chip-select control lines between each device and the host controller. Up to six general purpose outputs are provided, which can be used to access internal signals the LOCK signal, for example or to control front end components.
