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.
