General Description
The HMC704LP4E has been designed for the best
phase noise and lowest spurious content possible in
an integrated PLL.
Fabricated in a SiGe BiCMOS process, this
Fractional-N PLL con­sists of a very low noise digital
phase detector, VCO divider, reference divider and a
precision controlled charge pump.
Ultra low in-close phase noise and low spurious allows
wide loop bandwidths for faster fre­quency hopping and
low micro-phonics.
Exact frequency mode with 24-bit fractional mod­ulator
provides the ability to generate fractional frequencies
with zero frequency error, an important feature for
Digital Pre-Distortion systems.
The serial interface offers read back capability and is
compatible with a wide variety of protocols.
