Qorvo's RFFC5072 is a reconfigurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and a high linearity mixer. The fractional-N synthesizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The PLL/VCO engine combined with an external loop filter allows the user to generate local oscillator (LO) signals from 85MHz to 4200MHz. The LO signal is buffered and routed to the integrated RF mixer which is used to convert frequencies ranging from 30MHz to 6000MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption. RFFC5072 can be configured to work as a signal source by bypassing the integrated mixer. 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 (LOCK signal, for example) or to control front end components. The RFFC5072 operates with a 2.7V to 3.3V power supply.
