DESCRIPTION
The PLL620-20 is an XO IC specifically designed to work with high frequency fundamental and third overtone crystals. 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. It is ideal for XO applications requiring LVDS or PECL output levels at high frequencies.
