RFFC2071 2.7GHz RF Synthesizer/VCO with Integrated RF Mixer
The RFFC2071 is a re-configurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and 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 PLL/VCO engine combined with an external loop filter allows the user to generate local oscillator (LO) signals from 85MHz to 2700MHz. The LO signal is buffered and routed to the integrated RF mixers which are used to up/down-convert frequencies ranging from 30MHz to 2700MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption.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 (e.g. the LOCK signal) or to control front end components. The device operates with a 2.7V to 3.3V power supply.
