Programmable SiT9120A-B120001 differential oscillators eliminate long lead times and customization costs of legacy quartz oscillators. Engineered for reliability and robustness in demanding environments, they deliver 0.6 ps (typ.) integrated RMS phase jitter (12 kHz to 20 MHz) and excellent frequency stability as low as ±20 ppm. A 100% drop-in replacement for quartz, SAW, and overtone oscillators, these differential oscillators integrate seamlessly into GPS/GNSS modules, PCIe, and system clocking applications without requiring circuit or layout changes.
