• Thickness 10 mil.
DESCRIPTION
PLL520-10 is a VCXO IC specifically designed to
pull frequency fundamental crystals from 65MHz to
130MHz, with an integrated Phase Locked Loop for
selectable 1x (no PLL), 2x, 4x or 8x multipliers. Its
design was optimized to tolerate higher limits of
interelectrode capacitance and bonding capacitance
to improve yield. It achieves very low current into the
crystal resulting in better overall stability. Its internal
varicaps allow an on chip frequency pulling,
controlled by the VCON input.
