Functional Diagram
Dc - 7 GHz FrActionAL-n DiviDer is a fractional iD frequency divider targeted for fractional-n frequency synthesis, and stand-alone low noise frequency iv divider applications that require exceptional spurious performance. y D Although the Dc - 7 GHz FrActionAL-n DiviDer c can work with any vco and/or compatible Phase n Detector, best performance and features will be achieved when paired with the companion part, the e HMc984LP4e. u Fabricated in siGe BicMos process, the q Dc - 7 GHz FrActionAL-n DiviDer features a e 48-bit Delta sigma Fractional Modulator (DsM) with r programmable phase accumulator size, enabling F precise control of frequency step size and resolution. integrated DsM can generate frequencies with nearly 0 Hz frequency error. the DsM also includes a built-in programmable frequency sweep capability, with various automatic and user defined sweep modes and triggering options, including hardware trigger pin, or sPi trigger with optional delayed trigger. Dc - 7 GHz FrActionAL-n DiviDer is a versatile part capable of various configurations. it has 5 general purpose i/os (GPios). DsM outputs are made available from the GPio port, enabling the Dc - 7 GHz FrActionAL-n DiviDer to import and/ or export DsM sequences for various configuration options. Dc - 7 GHz FrActionAL-n DiviDer divider outputs are differential, open col ector with programmable Product covered by US and Foreign Patents including US Pat.
