Ref. divider RFFC2071A Synth Phase det. Ref. divider RFFC2072A RFFC2071A/2A 2.7GHz RF SYNTHESIZER/VCO WITH INTEGRATED RF MIXER The RFFC2071A and RFFC2072A are re-configurable frequency conversion devices 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- sizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The VCO features temperature compensation circuits that deliver stable performance across the operating temperature range of -40°C to +85°C. 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 cur- 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- ing 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. Both devices operate with a 2.7V to 3.3V power supply.
