Synth Ref. divider Phase det. Synth Ref. divider Functional Block Diagram Product Description 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 synthesizer 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 ...
