RFFC2071A/2A 2.7GHz RF SYNTHESIZER/VCO WITH INTEGRATED RF MIXER Package: QFN, 32-Pin, 5mm x 5mm RFFC2071A RFFC2072A Features 85MHz to 2700MHz LO Frequency Range Phase Phase Fractional-N Synthesizer with Synth Synth det. det. Very Low Spurious Levels Typical Step Size 1.5Hz Fully Integrated Low Phase Noise VCO and LO Buffers Ref. Ref. Integrated Phase Noise divider divider 0.18rms at 1GHz High Linearity RF Mixer(s) 30MHz to 2700MHz Mixer Functional Block Diagram Frequency Range Input IP3 +23dBm Product Description Mixer Bias Adjustable for Low The RFFC2071A and RFFC2072A are re-configurable frequency conversion devices Power Operation with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and either one or two high linearity mixers. The fractional-N synthe- Full Duplex Mode (RFFC2071A) sizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine 2.7V to 3.3V Power Supply step sizes and low spurious products. The VCO features temperature compensation Low Current Consumption circuits that deliver stable performance across the operating temperature range of -40C to +85C. The PLL/VCO engine combined with an external loop filter allows 3- or 4-Wire Serial Interface 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 Applications up/down-convert frequencies ranging from 30MHz to 2700MHz. The mixer bias cur- CATV Head-Ends rent is programmable and can be reduced for applications requiring lower power consumption. Both devices can be configured to work as signal sources by bypass- Digital TV Repeaters ing the integrated mixers. Device programming is achieved via a simple 3-wire serial Multi-Dwelling Units interface. In addition, a unique programming mode allows up to four devices to be Diversity Receivers 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 Software Defined Radios purpose outputs are provided, which can be used to access internal signals (the Frequency Band Shifters LOCK signal, for example) or to control front end components. Both devices operate with a 2.7V to 3.3V power supply.
