Product Series
| The Epoch Platform OCXO (SiT7101) operates from 10 to 250 MHz and delivers ±0.05 ppb stability in a 9.0 x 7.0 mm, 0.35-gram package for PNT holdover applications where GNSS signal loss is a design constraint. MHz Super-TCXOs (SiT5146 through SiT5543) cover 1 to 220 MHz with stability from ±0.05 ppm to ±2.5 ppm across operating ranges to -55°C to 105°C, supporting navigation, vehicle communications, and UAV applications where temperature variation drives timing error. |  |

| Low-noise Super-TCXOs (SiT7201/2) deliver phase noise to -159 dBc/Hz at 10 kHz offset for a 19.2 MHz carrier. across -55°C to +125°C. Both support RF front ends and tactical communications where vibration-induced phase noise degradation in quartz is a design concern. |  |

| Differential oscillators (SiT9346 through SiT9551) span 1 to 900 MHz with LVPECL, LVDS, and HCSL output options and 0.21 ps RMS jitter, supporting high-speed digital interfaces in radar, electronic warfare (EW), and communications backplane designs. The SiT7910 32.768 kHz Super-TCXO targets pulse-per-second timekeeping, achieving GNSS signal lock in seconds compared to 30 or more seconds with legacy quartz references, while operating at 6 µA supply current for battery-dependent portable and manpack equipment. |  |
