FEATURES
DESCRIPTIONS
PLL520-30 is a VCXO IC specifically designed to
pull frequency fundamental crystals from 65MHz to
130MHz, with selectable PECL or LVDS outputs. Its
design was optimized to tolerate higher limits of
interelectrodes 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.
