HMC983LP5ETR Descrizione generale

HMC983LP5E is a fractional frequency divider targeted for fractional-N frequency synthesis, and stand-alone low noise frequency divider applications that require exceptional spurious performance.

Although the HMC983LP5E can work with any VCO and/or compatible Phase Detector, best performance and features will be achieved when paired with the companion part, the HMC984LP4E.

Fabricated in SiGe BiCMOS process, the HMC983LP5E features a 48-bit Delta Sigma Fractional Modulator (DSM) with programmable phase accumulator size, enabling 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.

HMC983LP5E 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 HMC983LP5E to import and/or export DSM sequences for various configuration options.

HMC983LP5E divider outputs are differential, open collector with programmable current to accommodate different off-chip loads.
