Ref. divider Synth Functional Block Diagram Product Description The RFFC5061 and RFFC5062 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 RFFC5061 and RFFC5062 have been designed to use an external crystal, typically 26MHz, and have integrated programmable loading capacitors. The PLL...
