HMC703LP4E Product Details

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 phasenoise 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, doublebuffering, exact frequency control, phase modulation and more - while maintaining pin compatibility with the HMC700LP4E PLL. Exact frequency mode with a 24-bit fractional modulator provides the ability to generate fractional frequencies with zero frequency error and very low channel spurious, an important feature for Digital PreDistortion systems. The serial interface offers read back capability and is compatible with a wide variety of protocols.
