Although the Dc - 7 GHz Fr Action AL-n Divi Der can work with any vco and/or compatible Phase Detector, best performance and features will be achieved when paired with the companion part, the HMc 984LP4e. Fabricated in siGe BicMos process, the Dc - 7 GHz Fr Action AL-n DiviDer features a 48-bit Delta sigma Fractional Modulator (DsM) with programmable phase accumulator size, enabling precise control of frequency step size and resolution. integrated Ds M can generate frequencies with nearly 0 Hz frequency error. t he Ds M 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 s Pi trigger with optional delayed trigger. Dc - 7 GHz Fr Action AL-n Divi Der 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 Fr Action AL-n Divi Der to import and/ or export DsM sequences for various configuration options. Dc - 7 GHz Fr Action AL-n Divi Der divider outputs are differential, open collector with programmable Product covered by US and Foreign Patents including US Pat.
