General Description
The HMC703LP4E fractional synthesizer is built upon
the high performance PLL platform also contained in
the HMC704LP4E and Hittite’s latest generation of
PLL+VCO products. This platform has the best phase-
noise and spurious performance in the industry -
enabling higher order modulation schemes while
minimizing blocker effects in high performance radios.
In addition, the HMC703LP4E offers frequency sweep
and modulation features, external triggering, double-
buffering, exact frequency control, phase modulation
and more - while maintaining pin compatibility with the
HMC700LP4E PLL.
Exact frequency mode with a 24-bit fractional mod-
ulator provides the ability to generate fractional
frequencies with zero frequency error and very low
channel spurious, an important feature for Digital Pre-
Distortion systems.
The serial interface offers read back capability and is
compatible with a wide variety of protocols.
