FEATURES
DESCRIPTIONS
PLL520-28/-29 areVCXO IC specifically designed to
pull high frequency fundamental crystals. Their
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.
