The PLL520-05/-06/-07/-08/-09 is a family of VCXO
ICs specifically designed to pull high frequency
fundamental crystals. Their design was optimized to
tolerate higher limits of interelectrode capacitance
and bonding capacitance to improve yield. They
achieve very low current into the crystal resulting in
better overall stability. Their internal varicaps allow
an on chip frequency pulling, controlled by the
VCON input.
