1 / 6 page Preliminary PL623-38 Low Phase Noise XO (for 3rd O.T.) For 65-130MHz 47745 Fremont Blvd., Fremont, California 94538 TEL (510) 492-0990 FAX (510) 492-0991 www.phaselink.com Rev 05/03/05 Page 1 FEATURES • Input: 65-130MHz 3rd Overtone or fundamental Crystal • Output frequency: Up to 130MHz • Selectable /2, /4, /8 output dividers with 60KΩ pull up resistor on the selector pins • Available output: PECL • Supports 2.5V or 3.3V-Power Supply • Available in die form DESCRIPTION PL623-38 is an XO IC specifically designed to work with high frequency 3rd overtone or fundamental crystals from 65MHz to 135MHz. It requires an external resistor for the 3rd overtone selection. Its design was optimized to tolerate higher limits of inter-electrodes 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 PECL output levels at high frequencies.
